<P>PROBLEM TO BE SOLVED: To prevent closure of air passage due to invasion of liquid water into the air passage in a fuel cell separator. <P>SOLUTION: The fuel cell comprises a separator 10B between the mutually adjoining unit cells 10A. The separator comprises the air passage S1 at least on the surface side contacting with the air pole 12 of the fuel cell and a cooling space S2 as a cooling means, on the rear side, where the air and water are supplied, and the cooling space is communicated with the air passage through a communicating hole 143 formed in the separator, and the end part on the entrance side of the air passage is closed to the supply of the air and water by a lid 145 formed in one body at the end part of the separator. Thereby, the invasion of water in liquid state into the air passage is prevented without installing any special member. <P>COPYRIGHT: (C)2004,JPO |
