<P>PROBLEM TO BE SOLVED: To provide a solid polymer-type fuel cell having a high efficiency and a high output density even in case an entrance-neighboring region of a gas flow passage of a cathode catalyst layer becomes to have a dry atmosphere by supplying an oxidizer gas of a low humidity to the cathode in order to operate the solid polymer-type fuel cell system in the high efficiency. <P>SOLUTION: In the solid polymer-type fuel cell provided with an anode, a cathode, a polymer electrolyte membrane between them, and a separator in which the gas flow passage is formed that is arranged on the exterior side of the cathode and that has the entrance and the exit on a face contacted with the cathode, the catalyst layer of the cathode is made to be constituted so that the amount of platinum (alloy) and/or the amount of an ion exchange resin contained per unit area is larger in the entrance neighboring region than that in the exit neighboring region of the gas flow passage. <P>COPYRIGHT: (C)2003,JPO |
