<P>PROBLEM TO BE SOLVED: To prevent liquid junction by condensed water as far as possible with a simple structure. <P>SOLUTION: In a fuel cell 10, a first metal separator 16 and a second metal separator 18 are laminated in a horizontal direction to an electrode surface as a vertical surface, with interposing an electrolyte membrane and an electrode structure 14. An oxidant gas flow passage 26 extending in a gravity direction, an oxidant gas inlet communication hole 20a, and an oxidant gas outlet communication hole 20b are formed on a surface 16a of the first metal separator 16. A plurality of outlet connecting passages 28b communicating with the oxidant gas flow passage 26 and an oxidant gas outlet communication hole 20b are formed in a horizontal direction. In the outlet connecting passages 28b, a center in a displacement direction of the outlet connecting passages 28b is projecting to the side of the oxidant gas outlet communication hole 20b compared to both ends in a displacement direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
