<P>PROBLEM TO BE SOLVED: To enhance humidifying capacity of a porous separator from a cooling water flow channel to guided gas, if one is adopted for a fuel cell. <P>SOLUTION: Each unit cell of the fuel cell laminate includes a first separator plate 13 formed of a porous material arranged in adjacency to a fuel electrode and equipped with a groove forming a fuel gas flow channel 5 for supplying fuel gas to the fuel electrode with, and a second separator plate 14 formed of a porous material arranged in adjacency to an oxidant electrode and equipped with a groove forming an oxidant gas flow channel 6 for supplying oxidant gas to the oxidant electrode with. The fuel cell laminate includes a groove each forming a part of the cooling water flow channel at either of positions opposed to each other on a face where the first separator plate 13 and the second separator plate 14 of the adjacent unit cells are adjacent to each other, and these grooves are joined together to constitute the cooling water flow channel 12. <P>COPYRIGHT: (C)2009,JPO&INPIT |
