Abstract
A fuel cell system determines whether an operation condition of a fuel cell corresponds to a fuel gas shortage or an oxidation gas shortage. Upon determining that the fuel gas is in shortage, the system sets a lower voltage limit to be higher than that set when the system determines that the oxidation gas is in shortage. The system further controls an output voltage from the fuel cell so as to prevent output voltage from the fuel cell from decreasing below the lower voltage limit.
