<P>PROBLEM TO BE SOLVED: To provide a solid polymer fuel cell power generation system capable of continuing power generation operation without a problem even if there occurs an abnormality in a switching means to switch over the position of sub-stacks against the gas circulation direction. <P>SOLUTION: The power generation system has a first and a second sub-stacks 111, 112 connected so that a circulation route of hydrogen gas 1 may be in a series loop form, and is provided with main valves 101, 102 which connects and cut between a hydrogen gas supply source 130 and each sub-stacks 111, 112, main valves 103, 104 which connect and cut between the sub-stacks 111, 112, sub-valves 101b-104b installed in series and bypass valves 101a-104a installed in parallel to the valves 101-104, and a control device 140 which controls the valves 101-104 so as to switch over the positions of the sub-stacks 111-112 in gas circulation direction, and controls the valves 101a-104a, 101b-104b based on an information from voltmeters 141, 142. <P>COPYRIGHT: (C)2011,JPO&INPIT |
