ABSTRACT:
One or more defective fuel cells in fuel cell stacks are shortcircuited by a process comprising the steps of making plural holes in bipolar plates adjacent to the defective cell from at least one end of their process gas channels, inserting corrosion-resisting conductive wire rods into resultant holes to shortcircuit between the bipolar plates, and then closing the process gas channels of the bipolar plates at both ends with a heat-resisting sealing material to stop the supply the process gases to the defective cells.
