    摘要： Disclosed is a fuel cell stack comprising fuel cell units and first and second separators which are alternately stacked with each other. Wedge members are integrally inserted, over the plurality of fuel cell units, into communication holes of a fuel gas supply passage, an oxygen-containing gas supply passage, and a cooling water supply passage, as well as a fuel gas discharge passage, an oxygen-containing gas discharge passage, and a cooling water discharge passage. A fluid is uniformly delivered to each of the fuel cell units by the aid of the wedge members. Accordingly, the fluid of any one of a fuel gas, an oxygen-containing gas, and a cooling medium is uniformly delivered to each of the fuel cell units. Further, it is possible to simplify the arrangement of the fuel cell stack.

    摘要： A fuel cell stack comprises first and second separators for holding a fuel cell unit therebetween. The first separator has a fuel gas flow passage and the second separator has an oxygen-containing gas flow passage. The gas flow passages are formed by grooves with the number of grooves decreasing from the inlet to the outlet. In one embodiment, the gas flow passage comprises twelve individual first gas flow passage grooves which communicate with an inlet hole on a gas inlet side, six individual second gas flow passage grooves which communicate with the first gas flow passage grooves, and three individual third gas flow passage grooves which communicate with the second gas flow passage grooves. The third gas flow passage grooves communicate with an outlet hole on a gas outlet side.

    摘要： Disclosed is a fuel cell stack comprising a fuel cell unit and separators which are stacked with each other. The separator is provided with a cooling medium supply port corresponding to a central portion of an electrode power-generating section and a cooling medium discharge port corresponding to an outer circumferential portion of the electrode power-generating section. The cooling medium supply port communicates with the cooling medium discharge port via a cooling medium flow passage having a spiral configuration. Accordingly, the entire fuel cell unit can be uniformly cooled, and the power-generating function can be effectively improved.

    摘要： First gas flow passage grooves communicating with a fuel gas inlet and second gas flow passage grooves communicating with a fuel gas outlet are provided on a surface of a first separator. First and second united sections are provided at merged portions of the first gas flow passage grooves and the second gas flow passage grooves. Accordingly, the number of gas flow passage grooves is throttled from the side of the fuel gas inlet to the side of the fuel gas outlet. The turbulence is allowed to occur at the throttled portion to make it possible to improve the gas diffusion performance.

    摘要： A process for coating the inner wall surface of a thin tube having an inside diameter of 0.2 to 5 mm with a resin. The tube is first filled with a resin particulate dispersion. The dispersion filling the tube is held therein by its surface tension and does not flow out. A heater is positioned about the upper end of the tube and is moved down toward its lower end to heat the tube and thereby cause minute resin particles to adhere to its inner wall surface. Then, the tube is heated in a furnace and is cooled to have its inner wall surface coated with the resin.
