<P>PROBLEM TO BE SOLVED: To provide a power generation cell in which temporary repair can be carried out easily without stopping the operation even in the case breakage happens in the cell. <P>SOLUTION: The power generation cells 5 and separators 8 are laminated alternately to constitute a fuel cell stack. Then, in the vicinity of the fuel cell stack, a rod shaped body 21 is rotatably installed, provided with a conductive member 22 along the direction of the laminated layers. In the case the breakage arises in the power generation cells 5, the rod shaped body 21 is rotated to make the conductive member 22 contact the outer peripheral part of the neighboring upper and lower separators 8, 8, to make the broken power generation cells 5 electrically short circuited. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
