注目されている。2. Description of the Related Art A fuel cell is a device for generating electric energy from hydrogen obtained by reforming a fuel such as natural gas, methanol, naphtha, and coal, and oxygen in the air. You can Therefore, it is attracting attention as a promising new power generation system that can be used in various applications from space use to automobile use, large-scale power generation to small-scale power generation.

とにより発電を行っている。Particularly in recent years, a system using pure hydrogen as a fuel instead of using a reformed gas such as natural gas as a fuel has been proposed, and the power generation efficiency is higher because the hydrogen partial pressure is higher than that of the reformed gas. There is an advantage that it is also high. In such a system, pure hydrogen is filled in a hydrogen cylinder or the like, and power is generated by supplying pure hydrogen from the hydrogen cylinder to the anode.

め発電時間が短くなるという課題も有している。However, since the utilization rate of pure hydrogen in the battery reaction is generally about 90 to 95%, about 5 to 10% of pure hydrogen is discharged as unreacted hydrogen. Conventionally, unreacted hydrogen generated during cell reaction was discharged to the outside of the system after being burnt by a catalytic combustor, but a special device such as a catalytic combustor for catalytic combustion and an exhaust gas burner was separately provided. Since it is necessary, there is a problem that the system becomes large and the cost becomes high. There is also a problem that the generation time is shortened because the pure hydrogen in the cylinder cannot be used for 100% battery reaction.

Comparative Example 1 As shown in FIG. 3, unreacted pure hydrogen discharged from the fuel cell main body 11 is not recycled to the fuel cell main body 11, but is supplied by catalytic combustion via the unreacted hydrogen discharge pipe 52. A fuel cell system was manufactured in substantially the same manner as in Example 1 of the above-described first example except that the fuel was burned at 30 and then discharged to the outside of the system. In FIG. 3, reference numeral 40 is a catalytic combustor, 30 is an exhaust gas burner for supplying combustion gas to the catalytic combustor, and 21 is an MH cylinder filled with a hydrogen storage alloy.

程度と低いことに起因する。As a result, the operating time of the system (A) of the present invention was 110 minutes, while that of the system (X) of the comparative example was 100 minutes. Therefore, it is recognized that the operating time of the system (A) of the present invention is obviously longer than that of the system (X) of the comparative example. This is because, in the system (A) of the present invention, the utilization rate of pure hydrogen can be increased to about 100% by effectively recycling the unreacted hydrogen generated during the battery reaction, whereas the comparative example In (X) system, about 10% of unreacted hydrogen is discharged out of the system, so the utilization rate of pure hydrogen is 90%.
