Abstract: A fuel cell system comprises a fuel gas supply mechanism (1, 91-97) which supplies a fuel gas, an oxidizing gas supply mechanism (2) which supplies an oxidizing gas, a fuel cell (5) which generates power using the fuel gas supplied from the fuel gas supply mechanism (1, 91-97) and the oxidizing gas supplied from the oxidizing gas supply mechanism (2), and a water recovery device (41, 42) which separates and recovers water contained in exhaust gas from the fuel cell (5), and mixes the recovered water with a water-compatible liquid in the location where the water is separated and recovered.

Abstract: An aspect of the present invention provides a fuel cell apparatus that includes at least one fuel cell stack including a plurality of unit fuel cells, each unit fuel cell including a membrane electrode assembly including an electrolyte membrane and electrodes arranged on each side the electrode membrane, and a pair of separators sandwiching the membrane electrode assembly, a casing arranged and configured to accommodate the fuel cell stack, and at least one elastic member arranged part or whole of the circumference of the fuel cell stack in contact with an inner wall of the casing.

Abstract: A fuel cell system cooperating with a rechargeable battery (18) mounts a fuel cell (12) as a source of motive power in an electric vehicle with an electric motor. The fuel cell system and the rechargeable battery (18) supplies the electric motor with electrical power. The fuel cell system also includes a reformer (11) as a source of hydrogen hydrogen-containing gas supplied to the fuel cell (12). The fuel cell system comprises a temperature sensor (19) for measuring the temperature (Tb) of the rechargeable battery and a controller (16) for controlling the response characteristics (mainly the response characteristics of the reformer) of the fuel cell system based on the measured temperature (Tb). The controller (16) calculates a response time of the fuel cell system based on the measured temperature, and controls the supply of hydrogen-containing gas to the fuel cell in response to the calculated response time.

Abstract: Acrylic urethane paint composition for forming a hard coat layer of a paint-substitution film fixed on a molded plastic article. The acrylic urethane paint composition comprises a two-part acrylic urethane resin component including acrylic polyol dissolved in an aprotic organic solvent, and a prepolymer having not less than di-functional isocyanate group. Additionally, hydrophobic silica particulate is dispersed in the two part acrylic urethane resin component and has a diameter ranging from 5 to 300 nm. Hydroxyl groups existing at surface of said silica particulate being substituted with hydrophobic groups at a substitution percentage of not less than 15%.
