<P>PROBLEM TO BE SOLVED: To provide a fuel cell capable of suppressing generation and detention of liquid water in a reaction gas flow channel, and downsizing in a lamination direction of a power generation cell. <P>SOLUTION: The fuel cell is provided with a first separator 11 with at least a part of its cross section corrugated with a recess part of one face forming an oxidant gas flow channel and another recess part of another face forming a cooling medium flow channel. The oxidant gas flow channel and the cooling medium flow channel have a serpentine shape folded toward the same direction by folding parts, and are connected to a manifold through a manifold communication part at both an inlet side and an outlet side. The manifold communication part and the folded parts consist of a plurality of protruded parts formed in a lattice-point shape, the manifold at the inlet side of the cooling medium flow channel communicating part is adjacent to the manifold and the manifold communicating part of the inlet side of the oxidant gas flow channel, and the oxidant gas flowing in the oxidant gas flow channel and the cooling medium flowing in the cooling medium flow channel flow in the same direction. <P>COPYRIGHT: (C)2007,JPO&INPIT |
