<P>PROBLEM TO BE SOLVED: To suppress dew condensation on a cathode while the power generation capacity of a fuel cell is kept. <P>SOLUTION: In a separator 105 on a cathode side, at least two passages 1051, 1052 are formed as an oxygen diffusion passage diffusing oxygen as oxidant gas on the cathode. The first diffusion passage 1051 is formed in a first region 105a of the separator on the cathode side, and a second diffusion passage 1052 is formed separately from the first diffusion passage 1051 in a second region 105b being adjacent to the downstream side in the actual passing direction F1 of oxygen in the separator 105 on the cathode side than the first region 105a. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
