摘要： A fuel cell comprises a cathode catalyst layer and an anode catalyst layer disposed on each surface of an electrolyte membrane, an oxidant gas passage facing the cathode catalyst layer, and a fuel gas passage facing the anode catalyst layer. The cathode catalyst layer contains a metal catalyst. In a region (A), in which the differential electric potential between the cathode catalyst layer and the electrolyte membrane is larger than in another region, the metal catalyst content of the cathode catalyst layer or the specific surface area of the metal catalyst in the form of minute particles is increased, and thus a deterioration in electric power generation efficiency caused by melting of the metal catalyst due to the large differential electric potential is prevented.

摘要： Voltage rising detection unit detects a voltage rising condition of a fuel cell stack after the supply of reactant gas to the fuel cell stack is started. A control unit determines an internal state of the fuel cell stack on the basis of the detected voltage rising condition of the fuel cell stack, and then decides a subsequent operation of the fuel cell stack in accordance with the determination. This makes it possible to minimize deterioration of the fuel cell stack which is caused by generating power continuously in an unsuitable state.
