    • In a fluid leakage detection apparatus, hydrogen is supplied from a hydrogen tank to an FC stack of a fuel cell via first and second pipes. An inlet valve is provided between the hydrogen tank and the first pipe, and an outlet valve is provided between the first pipe and the second pipe. A controller serves to control valve opening a valve closing operation of the inlet and outlet valves, respectively. Those valves are closed in a state where the pressure within the hydrogen tank is made lower than the pressure within the first pipe, and the pressure within the second pipe is made lower than the pressure within the first pipe by operating those valves. Thereafter, the increase or decrease in the pressure within the first pipe is detected by a pressure gauge such that the leakage in the inlet valve or the outlet valve is determined. This makes it possible to detect the leakage both in the inlet valve and the outlet valve at the same time.
    • 在流体泄漏检测装置中,氢经由第一和第二管道从氢罐供应到燃料电池的FC堆叠。 在氢罐和第一管之间设有入口阀,在第一管和第二管之间设有出口阀。 控制器用于分别控制阀门打开入口和出口阀的关闭阀门。 这些阀在氢罐内的压力低于第一管内的压力的状态下封闭,并且通过操作这些阀,使第二管内的压力低于第一管内的压力。 此后,通过压力表检测第一管内的压力的增加或减小,从而确定入口阀或出口阀的泄漏。 这样可以同时检测入口阀和出口阀的泄漏。

    • A fuel cell system includes a fuel-cell stack 2 which generates electric power by utilizing a fuel gas and an oxidizing agent gas; a combusting device 3 which burns an off gas of the fuel gas emitted from the fuel-cell stack 2; an oxidizing agent gas supply device 4 including a turbine 41 and a compressor 43. The turbine 41 is rotated by the combustion energy of an exhausted gas from the combusting device 3. The compressor 43 is coupled to the turbine 41 to pressurize the oxidizing agent gas. The oxidizing agent gas supply device 4 is connected to the fuel-cell stack 2 for supplying the pressurized oxidizing agent gas. A reforming device 1 reforms a carbon hydride family fuel into fuel gas and a compressor 51 further pressurizes the pressurized oxidizing agent gas. The compressor 51 is connected between the reforming device 1 and the fuel-cell stack 2.

    • A fuel cell includes a plurality of laminated gas chambers, a plurality of separators that separate the gas chambers, intake passages for supplying fuel gas and oxidizing gas, exhaust passages for emitting the fuel gas and the oxidizing gas, intake ports to supply fuel gas and oxidizing gas from the intake passages to the gas chambers, exit ports to exit the fuel gas and the oxidizing gas from the gas chambers to the exhaust passages, and rectifying plates located at one end of the intake ports and extending across at least one of the gas intake passages. Each of the rectifying plates effectively restricts direct gas flow from one of the intake passages to the intake ports. Therefore, the number of gas chambers can be increased as compared to conventional fuel cells. Even though the number of gas chambers is increased, each gas chamber uniformly receives gas due to the excellent gas distribution achieved by the rectifying plates.
    • 燃料电池包括多个层压气室,分离气室的多个分离器,用于供应燃料气体和氧化气体的进气通道,用于排出燃料气体和氧化气体的排气通道,供应燃料气体的进气口和 从进气通道向气室氧化气体,出口以将燃料气体和氧化气体从气室排出到排气通道;以及整流板,其位于进气端口的一端并延伸穿过至少一个 进气通道 每个整流板有效地限制从一个进气通道到进气口的直接气流。 因此,与常规燃料电池相比,可以增加气室的数量。 即使气室的数量增加,由于整流板实现的优异的气体分布,各气室均匀地接收气体。

    • An air bag module comprises a housing for being mounted on a vehicle body and a cover fixedly secured on the housing. The housing has a base plate portion and a support plate portion bent down from the base plate portion. The support plate portion is provided with engagement holes. The cover has a cover portion having dimensions sufficient to cover the base plate portion of said housing, a substantially-cylindrical mounting plate portion extending from the cover portion toward the housing and located outside the support plate portion, short cylindrical convexities maintained in engagement with the engagement holes, and indentations formed in the mounting plate portion at plural locations spaced from each other in a peripheral direction of the mounting plate portion. The short cylindrical convexities are formed on the mounting plate portion and are located on a single plane extending across a direction in which the cylindrical mounting plate portion extends. Deepest portions of the indentations are substantially coincided with the single plane.
