    摘要: A fuel cell system, includes: 1) a fuel cell including: i) a fuel electrode to which a fuel gas is supplied, and ii) an oxidant electrode to which an oxidant gas reacting with the fuel gas for a generating operation is supplied; and 2) a fuel gas supplier supplying the fuel gas to the fuel electrode before the fuel cell system is started for the generating operation. A first predetermined pressure Pin1 of fuel gas is determined based on a product which is calculated from the following: i) an allowable volume Vcell for the fuel gas to flow in the fuel electrode, multiplied by, ii) a pressure Pcell of the fuel gas in the fuel electrode.

    摘要: At system shutdown, supply of hydrogen to a fuel electrode of a fuel cell stack is stopped, and at the same time dry air is supplied to an oxidant electrode. The dry air is subsequently supplied also to the fuel electrode, and finally the system is shut down. This allows optimal conditioning of a fuel cell at system shutdown, and effectively suppresses deterioration of a proton exchange membrane or a catalyst layer of the fuel cell which is caused at system shutdown as well as during storage. Furthermore, a fuel cell system excellent in safety and the like can be provided.

    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.
