<P>PROBLEM TO BE SOLVED: To suppress deterioration of power generation performance while suppressing leakage of gas in a fuel cell. <P>SOLUTION: The fuel cell has a power generation body having an electrolyte layer and a gas diffusion electrode layer arranged on both sides of the electrolyte layer and a separator arranged on both sides of the power generation body. The fuel cell also has a gasket which is arranged so as to contact at least a part of the end face of the power generation body in order to suppress leakage of gas to the outside and circulation of gas between the gas diffusion electrode layers on both sides of the electrolyte layer. The power generation body comprises a jointing part which is an end part jointed to the gasket and an operating part which is located more inside than the jointing part and is a portion directly contacting the separator. The shapes of the power generation body and the separator are established so that the surface pressure which the operating part of the power generation body receives from the separator is the value or more of the surface pressure which the jointing part of the power generation body receives from the separator. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
