<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of recovering the power generation performance of a fuel cell while suppressing the deterioration of the durability of the fuel cell. <P>SOLUTION: The fuel cell system 100 has a fuel cell 10 and potential control means 30, 60, 80. The fuel cell 10 includes platinum as an electrode catalyst. The potential control means 30, 60, 80 recover the power generation performance of the fuel cell 10 by lowering the air electrode potential of the fuel cell 10 to potential higher by 0.6 V with respect to that of a reversible hydrogen electrode. <P>COPYRIGHT: (C)2010,JPO&INPIT |
