Description
Technical Field
The invention relates to a fuel cell, in particular to a dual-fuel cell power system capable of operating in parallel.
Background
An electrochemical fuel cell is a device capable of converting hydrogen and an oxidant into electrical energy and reaction products. The inner core component of the device is a Membrane Electrode (MEA), which is composed of a proton exchange Membrane and two porous conductive materials sandwiched between two surfaces of the Membrane, such as carbon paper. The membrane contains a uniform and finely dispersed catalyst, such as a platinum metal catalyst, for initiating an electrochemical reaction at the interface between the membrane and the carbon paper. The electrons generated in the electrochemical reaction process can be led out by conductive objects at two sides of the membrane electrode through an external circuit to form a current loop.
At the anode end of the membrane electrode, fuel can permeate through a porous diffusion material (carbon paper) and undergo electrochemical reaction on the surface of a catalyst to lose electrons to form positive ions, and the positive ions can pass through a proton exchange membrane through migration to reach the cathode end at the other end of the membrane electrode. At the cathode end of the membrane electrode, a gas containing an oxidant (e.g., oxygen), such as air, forms negative ions by permeating through a porous diffusion material (carbon paper) and electrochemically reacting on the surface of the catalyst to give electrons. The anions formed at the cathode end react with the positive ions transferred from the anode end to form reaction products.
In a pem fuel cell using hydrogen as the fuel and oxygen-containing air as the oxidant (or pure oxygen as the oxidant), the catalytic electrochemical reaction of the fuel hydrogen in the anode region produces hydrogen cations (or protons). The proton exchange membrane assists the migration of positive hydrogen ions from the anode region tothe cathode region. In addition, the proton exchange membrane separates the hydrogen-containing fuel gas stream from the oxygen-containing gas stream so that they do not mix with each other to cause explosive reactions.
In the cathode region, oxygen gains electrons on the catalyst surface, forming negative ions, which react with the hydrogen positive ions transported from the anode region to produce water as a reaction product. In a proton exchange membrane fuel cell using hydrogen, air (oxygen), the anode reaction and the cathode reaction can be expressed by the following equations:
and (3) anode reaction:
and (3) cathode reaction:
in a typical pem fuel cell, a Membrane Electrode (MEA) is generally placed between two conductive plates, and the surface of each guide plate in contact with the MEA is die-cast, stamped, or mechanically milled to form at least one or more channels. The flow guide polar plates can be polar plates made of metal materials or polar plates made of graphite materials. The fluid pore channels and the diversion trenches on the diversion polar plates respectively guide the fuel and the oxidant into the anode area and the cathode area on two sides of the membrane electrode. In the structure of a single proton exchange membrane fuel cell, only one membrane electrode is present, and a guide plate of anode fuel and a guide plate of cathode oxidant are respectively arranged on two sides of the membrane electrode. The guide plates are used as current collector plates and mechanical supports at two sides of the membrane electrode, and the guide grooves on the guide plates are also used as channels for fuel and oxidant to enter the surfaces of the anode and the cathode and as channels for taking away water generated in the operation process of the fuel cell.
In order to increase the total power of the whole proton exchange membrane fuel cell, two or more single cells can be connected in series to form a battery pack in a straight-stacked manner or connected in a flat-laid manner to form a battery pack. In the direct-stacking and serial-type battery pack, two surfaces of one polar plate can be provided with flow guide grooves, wherein one surface can be used as an anode flow guide surface of one membrane electrode, and the other surface can be used as a cathode flow guide surface of another adjacent membrane electrode, and the polar plate is called a bipolar plate. A series of cells are connected together in a manner to form a battery pack. The battery pack is generally fastened together into one body by a front end plate, a rear end plate and a tie rod.
A typical battery pack generally includes: (1) the fuel (such as hydrogen, methanol or hydrogen-rich gas obtained by reforming methanol, natural gas and gasoline) and the oxidant (mainly oxygen or air) are uniformly distributed in the diversion trenches of the anode surface and the cathode surface; (2) the inlet and outlet of cooling fluid (such as water) and the flow guide channel uniformly distribute the cooling fluid into the cooling channels in each battery pack, and the heat generated by the electrochemical exothermic reaction of hydrogen and oxygen in the fuel cell is absorbed and taken out of the battery pack for heat dissipation; (3) the outlets of the fuel gas and the oxidant gas and the corresponding flow guide channels can carry out liquid and vapor water generated in the fuel cell when the fuel gas and the oxidant gas are discharged. Typically, all fuel, oxidant, and cooling fluid inlets and outlets are provided in one or both end plates of the fuel cell stack.
The proton exchange membrane fuel cell can be used as a power system of vehicles, ships and other vehicles, and can also be used as a movable and fixed power generation device.
When the proton exchange membrane fuel cell is used as a vehicle power system, a ship power system or a mobile and fixed power station, the proton exchange membrane fuel cell must comprise a cell stack, a fuel hydrogen supply subsystem, an air supply subsystem, a cooling and heat dissipation subsystem, an automatic control part and an electric energy output part.
Fig. 1 is a fuel cell power generation system, and 1 in fig. 1 is a fuel cell stack; 2 is a hydrogen storage bottle or other hydrogen storage devices; 3 is a pressure reducing valve; 4 is an air filtering device; 5 is an air compression supply device; 6 is a hydrogen water-steam separator; 6' is an air water-steam separator; 7 is a water tank; 8 is a cooling fluid circulating pump; 9 is a radiator; and 10 is a hydrogen circulating pump.
Currently, fuel cell power generation systems are used in vehicle power systems or as power plants, all of which require high power output. This high power output is reflected in the fact that the fuel cell stack must require a high voltage, high current output.
In practical application, a high-power fuel cell stack is realized by a method of forming a large fuel cell stack with a compact volume by integrating a plurality of fuel cell stack modules.
For example, in the method of US Patent 5486430, a plurality of fuel cell stacks are arranged in parallel, and all the inlets and outlets of air, hydrogen and cooling water of each fuel cell stack are integrated into a common front panel. The front panel has six fluid channels shared by the inlet and outlet of all air, hydrogen and cooling water on the fuel cell stack. As described in "an integrated fuel cell (patent No. 02265512.3)" of shanghai mystery technologies, a plurality of fuel cell stacksshare a collector plate on which a plurality of fuel cell stacks are integrated at the front and rear. The collecting panel is equivalent to the middle of a plurality of fuel cell stacks, and the inlets and outlets of air, hydrogen and cooling fluid of all the fuel cell stacks are uniformly integrated on the common collecting panel. The collecting panel is provided with six fluid channels shared by inlets and outlets of all air, hydrogen and cooling fluid on all fuel cell stacks.
Although each fuel cell stack module shares each fluid channel, each module has its own positive and negative current collecting mother board, and the whole integrated fuel cell can output the high voltage and large current requirements meeting the actual requirements by connecting the positive and negative mother boards on all the fuel cell modules in series and parallel.
For a fuel cell power generation system with higher power output, in principle, more fuel cell stack modules can be integrated, and the inlets and outlets of all air, hydrogen and cooling fluid on all the fuel cell stack modules share six fluid channels, i.e. the integrated large fuel cell stack is also an integrated structure with six fluid pipelines with inlets and outlets of total air, hydrogen and cooling fluid.
However, for fuel cell power generation systems with very high power output, for example: for a fuel cell power generation system with an output of more than 100KW, even more than several hundreds KW, the number of fuel cell stack modules to be integrated is too large, and the integration of such a large number of fuel cell stack modules into an integrated fuel cell with an integrated structure is difficult, even impossible from an engineering viewpoint, regardless of the integration method.

The purpose of the invention can be realized by the following technical scheme: a dual-fuel cell power system capable of running in parallel comprises a fuel cell stack, a fuel hydrogen supply subsystem, an air supply subsystem, a cooling fluid circulation subsystem, an automatic control and electric energy output subsystem, it is characterized in that the fuel cell stack comprises two sets of integrated fuel cell large stacks which are assembled in parallel, up and down or adjacent and close to each other, wherein, 2 hydrogen inlets in two sets of integrated fuel cell large stacks share a total hydrogen inlet pipe, 2 hydrogen outlets share a total hydrogen outlet pipe, 2 cooling fluid inlets share a total inlet cooling fluid pipe, 2 cooling fluid outlets share a total outlet cooling fluid pipe, 2 air inlets can share a total air inlet pipe, or can respectively and independently use an air inlet pipe, 2 air outlets can share a total air outlet pipe, or can respectively and independently use an air outlet pipe.
In the two sets of integrated fuel cell power systems, the fuel hydrogen supply subsystem can share one set of hydrogen storage and supply device and hydrogen control and circulation device.
In the two integrated fuel cell power systems, the cooling fluid circulation subsystem can share one cooling fluid circulation device, that is, only one cooling fluid circulation pump and one radiator are arranged in the whole cooling fluid circulation subsystem.
In the two integrated fuel cell power systems, the air supply subsystem may share a common air supply, or in the two integrated fuelcell power systems, the air supply subsystem may have two air supplies, with the air supply lines being separate.
In the two-sleeve integrated fuel cell power system, the automatic control and electric energy output subsystem performs unified integrated synchronous operation control, and two sets of integrated fuel cell large stacks can be connected in series or in parallel.
In the two sets of integrated fuel cell power systems, under the application condition of being used as a vehicle-mounted power source, asynchronous operation control can be carried out, namely, one set of integrated fuel cell large stack can be in a working state, and the other set of integrated fuel cell large stack is in a non-working state; that is, the power output of the whole power generation system is not output by two sets of parallel operation together, but can be output by a set alone when the power output is low, and output by two sets of parallel operation together when the power output is high.
The invention achieves the purpose of high power or super high power output by a double-fuel cell power generation system which can run in parallel without a method of blindly increasing the number of integrated fuel cell stack modules. The two sets of fuel cell power generation systems can run in parallel, but the two sets of integrated fuel cell large stacks in the two sets of fuel cell power generation systems are uniformly and integrally designed in the fuel hydrogen supply subsystem, the air supply subsystem, the cooling and heat dissipation subsystem, the automatic control and the electric energy output, so that the volume and the weight are reduced, the vehicle-mounted or fixed power generation needs are met, the synchronous control is unified, and the series and parallel connection of the output currents of the two sets of power generation systems can be realized, so that the needs of practical application purposes are met.
