<P>PROBLEM TO BE SOLVED: To provide a solid polymer type fuel cell power generation system which, even when operated for power generation continuously over a long time, can restrict the life of a solid polymer electrolyte membrane from deteriorating significantly. <P>SOLUTION: First to twelve gas valves 140A to 140L are controlled to make them opened or closed periodically so that fuel gas 1 from a fuel gas supply source 121 will be supplied from a mouth on the downstream side of fuel gas 1 circulation direction of a fuel gas passage in one of a first substack 111 and a second substack 112 located on the downstream side of the fuel gas 1 circulation direction to the fuel gas passage in one of the substacks, and that the fuel gas 1 having circulated the fuel gas passage in one of the substacks will be supplied to the fuel gas passage in the other one of the first substack 111 and the second substack 112. <P>COPYRIGHT: (C)2013,JPO&INPIT |
