<P>PROBLEM TO BE SOLVED: To provide a technology for suppressing dropping of power generation due to the enlargement of a defective power generation region in a fuel battery cell. <P>SOLUTION: A fuel cell system 1 comprises a membrane electrode assembly 16 in which an electrolyte film is joined to a catalyst layer, a conductive member 17 comprising a gas flow channel 20H where a fuel gas flows along the surface of catalyst layer, and a power supply part 6 which electrically connects a load to which power is supplied to the conducive member 17. In the conductive member 17, a particular section of gas flow channel is electrically insulated from other sections by an insulating member D. A power supply part comprises a control means 6A which turns on/off the connection between a particular section and a load. The control means 6A turns off the connection between the particular section and the load when the moisture content of the electrolyte film decreases during power generation by the membrane electrode assembly 16 while the connection between the particular section and the load is in on-state. <P>COPYRIGHT: (C)2010,JPO&INPIT |
