    摘要: A fuel cell system includes a fuel cell stack for generating power and power generation control means. The fuel cell stack has at least one cell that includes a cathode to which an oxidant is supplied, an anode to which a fuel is supplied, and a polymer electrolyte membrane sandwiched between the cathode and the anode. The power generation control means has dryness degree determination means for determining the degree of dryness of the fuel cell stack based on shut-down period. When the shut-down period is shorter than a predetermined period of time, the power generation control means supplies a gas for drying to the cathode for a predetermined period of time, to remove water remaining in the cathode. When the shut-down period is equal to or longer than the predetermined period of time, such a drying operation is not performed.

    摘要: A fuel cell system includes a fuel cell stack which is composed of an assembly of fuel cells, each of which is provided with an anode that is supplied with fuel and a cathode that is supplied with oxygen. The fuel cell system further includes an air duct for supplying oxygen, which is disposed along the fuel cell stack, and at least a fuel tank and a recovery tank unit of a gas-liquid separator, namely, a tank for supplying water to be mixed with fuel, which both are disposed on a side opposite to the fuel cell stack with the air duct interposed therebetween. Accordingly, vaporization of fuel due to heat generated in the fuel cell stack which is the power generating section is suppressed, and a deterioration of generating characteristics attributable to insufficient fuel supply is prevented.

    摘要: A scroll type compressor having high efficiency and high reliability is obtained by preventing leakage of a compression chamber, increasing air tightness thereof and securing a smooth motion of an orbiting scroll member. A second frame member supported by a first frame member and slightly movable in the axial direction is disposed in the rear of an orbiting scroll member. Force is applied to the rear of the second frame member, and a slight axial movement of the orbiting scroll member is regulated by a fixed scroll member and the second frame member. As a result, both the scroll members are in tight contact or close to each other with a small space, and a smooth movement thereof can be secured, which makes it possible to obtain a scroll type compressor having high efficiency and high reliability.
