<P>PROBLEM TO BE SOLVED: To provide a fuel cell for avoiding the corrosion of a catalyst resulting from fuel gas residing at starting/stopping while suppressing an increase in the number of components and dispensing with complicated control. <P>SOLUTION: A fuel pole catalyst layer 2a and an oxidizing agent pole catalyst layer 2b are arranged on one face of an electrolytic membrane 1 and on the other face thereof, respectively. A fuel pole separator 4a on which a fuel gas flow path 5a is formed and an oxidizing agent pole separator 4b on which an oxidizing agent gas flow path 5b is formed are provided on one face and on the other face, respectively, so that the catalyst layers 2a, 2b are held therebetween, to form a unit fuel cell. A joint member 7 of a conductive material is arranged in contact with the fuel pole separator 4a and the oxidizing agent pole separator 4b. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
