<P>PROBLEM TO BE SOLVED: To provide a fuel cell deterioration determination method capable of more reliably determining a deterioration state of a fuel cell body, and a fuel cell system. <P>SOLUTION: In this fuel cell deterioration determination method, a voltage of a fuel cell body generating power by a power generation reaction of fuel gas and an oxidant gas is monitored, and a deterioration state of the fuel cell body is determined according to an aging change of the voltage. The method includes the steps of: starting a stop process or starting process of the fuel cell body; measuring the voltage of the fuel cell body when an output of the fuel cell body, and a temperature of the fuel cell body or a flow rate of the fuel gas correspond to setting conditions in the stop process or the starting process; and comparing the measured voltage with a previous voltage to determine the deterioration state of the fuel cell body. <P>COPYRIGHT: (C)2013,JPO&INPIT |
