Abstract: Consumed hydrogen-off gas is discharged from a fuel cell via a hydrogen-off gas exhaust flow passage. Consumed oxygen-off gas is discharged from the fuel cell via an oxygen-off gas exhaust flow passage. The oxygen-off gas flowing through the oxygen-off gas exhaust flow passage and the hydrogen-off gas flowing through the hydrogen-off gas exhaust flow passage are mixed and diluted in a mixing portion. The gases mixed in the mixing portion flow into a combustor via a gas-liquid separator. The combustor, which includes a platinum catalyst, causes hydrogen contained in the mixed gases to react with oxygen by combustion and further reduces the concentration of hydrogen contained in the mixed gases. The mixed gases whose concentration of hydrogen has been reduced by the combustor is discharged to the atmosphere.

Abstract: A noise eliminator for a fuel cell has a noise elimination chamber that is filled with a noise elimination material, and also has discharge gas flow piping penetrating the noise elimination chamber and having holes in the peripheral wall of the piping and through which gas charged from the fuel cell flows. An electrically conductive material is added to the noise elimination material. The construction suppresses electrostatic charging even if discharge gas flows in the discharge gas flow piping.

Abstract: A fuel cell system of the present invention includes a fuel cell stack, a fuel system for supplying a fuel gas to the fuel cell stack, and on-off valves which form a closed space not including the fuel cell stack in the fuel system. The closed space is filled with an inspection gas from the on-off valve which functions also as an inspection gas inlet port. After completion of the inspection, the inspection gas in the closed space is discharged from the on-off valve which functions also as an inspection gas outlet port.

Abstract: A high-pressure switching valve device. A valve main body pressed to contact with an end face of a valve seat when the high-pressure switching valve device is closed, and a seal member pressed to contact with the end face of the valve seat when the high-pressure switching valve device is closed. When the high-pressure switching valve device is closed, the seal member is located on a high-pressure side and the valve main body is located on a low-pressure side.

Abstract: A liquid drain (2) includes a drain body (20). The drain body defines a float chamber (30) that is adapted to store a liquid. A liquid level adjusting mechanism serves to adjust the liquid level within the float chamber and includes a float (40; 240; 340; 440; 540). The float has a float body (42; 242; 342; 442; 542) that is adapted to float on the liquid surface within the float chamber. A damper (43; 46; 243; 343; 443) may inhibit or minimize a shaking phenomenon of the float body due to waving of the liquid within the float chamber.

Abstract: Gas/liquid separating devices include a separator (1) for separating a mixed gas/liquid flow (M). A liquid drain (2) communicates with the separator and defines a liquid storage chamber (30). The liquid drain serves to temporarily store a liquid separated from the mixed flow within the liquid storage chamber, so that a space that is not occupied by the liquid is ensured within the liquid storage chamber. An adjusting mechanism (52, 152) may serve to adjust the pressure within the space of the liquid storage chamber.

Abstract: In a gas valve including a valve body having an annular seal surface, of which an axis is disposed to extend in a vertical direction, and of which seal surface a diameter becomes larger toward a lower end of the seal surface, to prevent water drops on the seal surface made by condensation from freezing and to prevent the seal surface from being fixed to a seat because of the freezing, a liquid repellent film is provided on the seal surface of the valve body.

Abstract: A high-pressure tank in which the sealing ability and pressure-proof strength at a mouth portion are prevented from being lower by a high pressure within the tank, wherein the mouth portion 2 projects into the inside of the tank, and internal threads are formed on an inner peripheral surface of the mouth portion, and a thread member is threadedly engaged with the internal threads. Further, a seal member is provided between the mouth portion and the thread portion, and is disposed adjacent to the inner peripheral surface of the mouth portion adjacent to an inner end thereof disposed within the tank. A high pressure within the tank acts on an outer peripheral surface of the mouth portion while the atmospheric pressure acts on the inner peripheral surface of the mouth portion, so that the mouth portion is compressed radially inwardly, thereby preventing the loosening of the tightened seal member.

Abstract: In a solenoid valve, for preventing an elastic sheet used in a valve portion from being damaged by high-pressure gas flow, and without a seal in a wiring portion connected to a coil preventing pressure leakage from the wiring portion difficult to be sealed, particularly in a solenoid valve used for distribution control of high-pressure gas, a valve body is made of an inelastic material and dome-shaped, and a sheet surface facing the valve body is divided in a radial direction into an inelastic sheet surface closer to an axis of the valve body in a radial direction, and an elastic sheet surface far from the axis. The former is inclined to the valve body at a predetermined angle &thgr;1 to a line orthogonal to the axis of the valve body. The latter is inclined at an angle &thgr;2 larger than the angle &thgr;1 of the inelastic sheet surface. An elastic sheet surface in a boundary portion between the former and the latter is set on the same position as or lower than the inelastic sheet surface.

The valve main body 10 is constituted out of a high strength member and the seal member 9 is constituted out of an annular elastic member.
