Description of the Related Art In recent years, carbon-based materials such as carbon nanotubes, carbon nanofibers, and fullerenes have been attracting attention as a next-generation energy storage method because they are lightweight and occlude a large amount of hydrogen. It was difficult to fill to density. For example, carbon nanotubes and carbon nanofibers have a hydrogen storage capacity of 10 kg / m 3 per volume of the material itself and a filling rate of 50%, and the actual storage capacity is 5 kg / m 3 . Conventionally, platinum-supported carbon has been used as a catalyst for a fuel cell. That is, platinum having a catalytic function is miniaturized and supported on conductive carbon. Since platinum is expensive and its resources are limited, there are many issues to be overcome such as a rise in price if fuel cells become widespread and demand increases.

When the electrons e − flow to an external circuit toward the anode (air electrode), a direct current is generated. In a well-known fuel cell, a porous electrode as a positive electrode on one side of a cation exchange membrane and a porous electrode as a negative electrode on the other side are integrally bonded, and pure oxygen or air is supplied from the outside of the cell to the positive electrode. The hydrogen is supplied from the outside of the battery to the negative electrode, and power is generated by the following reaction.

In a fuel cell that generates an electric current, fullerenes are used as a catalyst film so that the environment can be adjusted and the catalyst function can be exhibited. In order to improve the environment, the catalyst film is irradiated with light or energized to utilize the energy to enhance the catalytic ability. The power for conditioning the environment is characterized by using a part of the generated power. Thus, fullerenes (fullerene,

In this fuel cell, an oxygen electrode is arranged on one side of a catalyst film and a cathode (hydrogen electrode) is arranged on the other side.

The storage of hydrogen in the fullerene electrode may be performed before or after forming the electrode. The battery system may be a closed system, and the primary battery type may be discarded if the hydrogen in the fullerenes is consumed by discharging. It can also be discharged. This is very practical in practice, since it is not necessary to always provide a complicated and large circulation system to the battery. For replenishing hydrogen to the fullerene electrode, the oxygen electrode (positive electrode) is made of, for example, a material mainly composed of a carbon nanotube carrying a platinum catalyst, and functions as a so-called hydrogen electrode. Using an electrode, instead of supplying oxygen or air to this positive electrode, hydrogen is supplied from the outside of the battery, and if electricity is supplied between this positive electrode and the carbon nanotube electrode (negative electrode), hydrogen is supplied to the negative electrode.
