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： For implementing a stop control which extracts a current from a fuel cell and consumes a cathode side oxygen at a system stop, the current extraction from the fuel cell is ended in a state that a certain quantity of oxygen smaller than when the current extraction is started remains on a cathode side of the fuel cell. With this, the hydrogen movement to the cathode side after the system stop can be effectively suppressed and thereby a cathode internal hydrogen concentration at the system start can be kept low, thus making it possible to properly process the cathode side hydrogen at the system start.
