Abstract
Provided is an aging device for a fuel cell stack, capable of reliably detecting the generation of a negative voltage during aging while also achieving a cost reduction with reduced cell monitors. The voltage of an end cell on the reactant gas inlet side, in which the voltage is likely to become the highest, is monitored alone, so that the generation of a negative voltage in each of a plurality of individual central cells other than the end cell is estimated.
