<P>PROBLEM TO BE SOLVED: To provide a fuel cell, in which mutual projections of separators adjacent in a laminated direction in a unit fuel cell do not cause or hardly cause contact failures or increase in the contact resistance due to mutual positional shift. <P>SOLUTION: (1) In the fuel cell, formed by laminating a plurality of unit cells each of which is formed by sandwiching an MEA with a first separator 13 having a first gas flow path 12 and a second separator 15 having a second gas flow path 14, the first gas flow path 12 of the first separator and the second gas flow path 14 of the second separator are formed into a rugged shape in a direction orthogonal to the cell surface direction and the flow path extending direction so as to mutually cross diagonally. (2) At portions diagonally crossing between the first gas flow path 12 of the first separator and the second gas flow path 14 of the second separator of an adjacent unit fuel cell, the first separator 13 and the second separator 15 of the adjacent unit fuel cell are fixed to each other. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
