<P>PROBLEM TO BE SOLVED: To provide an operating method for a solid polymer fuel cell which can contribute to longer life of the fuel cell and output recovery of a cell. <P>SOLUTION: In the operating method for a solid polymer fuel cell, a membrane-electrode assembly is dried up by circulating dry gas to a positive electrode or both electrodes upon stopping of power generation after a power generation operation. A solid polymer fuel cell system has a power generation operation mode, and a drying operation mode for drying the membrane-electrode assembly by circulating the dry gas to the positive electrode or both electrodes upon stopping of power generation. <P>COPYRIGHT: (C)2011,JPO&INPIT |
