[0029] figure 1 It is an explanatory view showing the planar state of the catalytic reaction plane region and the conductive member in the fuel cell of the first embodiment of the present invention. In addition, figure 2 It is an explanatory diagram showing a partial cross-sectional state of the fuel cell of the first embodiment.
[0030] Such as figure 1 As shown, in the fuel cell 1 of the present embodiment, the energizing member 40 is arranged outside the catalyst reaction plane region A. In addition, such as figure 1 As shown, the fuel cell 1 of the present embodiment includes: gas sealing members 50, 52 formed of a conventionally known material that are arranged outside the catalyst reaction plane region A and closer to the catalyst reaction plane region A side than the energizing member 40 (Reference figure 2 . ). Furthermore, a manifold M for fuel gas, oxidant gas, and refrigerant is also provided.
[0031] In addition, such as figure 2 As shown, the fuel cell 1 of ...

[0041] image 3 It is an explanatory diagram showing the planar state of the catalytic reaction plane region and the conductive member in the fuel cell of the second embodiment of the present invention. In addition, Figure 4 It is an explanatory diagram showing a partial cross-sectional state of the fuel cell of the second embodiment. It should be noted that the same parts as those already described in the first embodiment are given the same reference numerals and their description is omitted.
[0042] Such as image 3 with Figure 4 As shown, the fuel cell of the present embodiment has the following differences: (1) the gas sealing member 50 is arranged closer to the outside than the energizing member 40; and (2) is not provided between the diaphragm 30 and the other diaphragm 30' The elastic member 70 is arranged intermittently and outside the catalyst reaction plane region A to relieve stress generated between the diaphragm 30 and the other diaphragm 30'.

[0056] Figure 8 It is an explanatory diagram showing the planar state of the catalytic reaction plane region and the conductive member in the fuel cell of the sixth embodiment of the present invention. It should be noted that the same parts as those described in the first to fifth embodiments are given the same reference numerals and their description is omitted.
[0057] Such as Figure 8 As shown, the fuel cell of this embodiment has a configuration in which two energizing members are arranged in the outer peripheral region B of the catalyst reaction plane region A, and they are arranged along the longitudinal direction X of the catalyst reaction plane region.
[0058] Therefore, the electron moving distance from the catalytic reaction plane region to the energizing member is relatively short, and therefore the electrical resistance can be reduced.
[0059] As a result, it is possible to significantly suppress the corrosion of the fuel cell and realize more excellent power generat...
