摘要： The invention provides a polymer electrolyte fuel cell device 1 comprising at least one fuel cell 10 having an anode, a cathode and a polymer electrolyte membrane provided between the anode and cathode, a combustion unit 3, a fuel gas pipe 4 for introducing therethrough the unreacted portion of a fuel gas discharged from the fuel cell 10 into the combustion unit 3, and an oxidizer gas supply manifold 2 for supplying oxidizer gas discharged from the combustion unit 3 to the cathode. By partly consuming the oxygen contained in an oxidizer gas supplied from outside, the combustion unit 3 burns the unreacted fuel gas and burns the impurities contained in the oxidizer gas. This feature prevents the polymer electrolyte membrane from drying, affords a high cell voltage without impairment and enables the device to achieve a higher overall efficiency than in the prior art.

摘要： A hydrogen-absorbing alloy electrode utilizes as an electrode material a hydrogen-absorbing alloy having selectively oriented crystals, which is expressed in terms of a specific maximum value obtained from analysis of powder X-ray diffractometry. This electrode, in which the hydrogen-absorbing alloy used is hardly pulverized upon repeated charge-discharge cycles and oxidation thereof is suppressed, gives metal hydride alkaline secondary batteries having excellent cycle characteristics. A method for evaluating hydogen-absorbing alloys for electrode comprises, utilizing the fact that there exists a clear relationship between specific parameters obtained by analyzing data based on the hydrogen-absorbing alloy to be evaluated and the characteristics of the electrode obtained therefrom, preparing and using analytical curves with the specific parameters. This method can evaluate rapidly and precisely various characteristics of hydrogen-absorbing alloys for electrode, without actually fabricating test cells therefrom.

摘要： The object of the present invention is to provide fuel cell including a cell that is formed by sandwiching solid polymer membrane between an anode and a cathode that generates electricity with stability and high performance by evenly moistening the solid polymer membrane. For this purpose, in a gas diffusion layer 24, which is positioned adjacent to a cathode catalyst layer 22, the content of fluororesin in an area on the side of the entrance for the oxidizer is set to be higher than in another area on the side of the exit so that the water repellency in the entrance side area is higher than in the exit side area. As a result, a water permeation suppressing part 24A, where the water permeability is relatively low, is formed in the area on the entrance side, while a water permeable part 24B, where the water permeability is relatively high, is formed in the area on the exit side.

摘要： Molten steel is efficiently vacuum treated in a vacuum treatment vessel provided with a top blow lance capable of injecting oxygen and a gaseous fuel at desired flow rates, respectively, into the molten steel. The blow lance is provided on the top of the vacuum treatment vessel and is supported so as to be freely vertically movable. By spacing the lower end of the top blow lance not more than 2 m from the surface of the molten steel bath and injecting only oxygen onto the molten steel, and spacing the lower end of the top blow lance 1.0 m or more from the surface of the molten steel bath and injecting both oxygen and a gaseous fuel gas onto the molten steel, the temperature of the molten steel is prevented from decreasing during the vacuum treatment and the molten steel is so prevented from depositing on the inside wall of the vacuum treatment vessel. The top blow lance includes an oxygen injection section having a throat and a tapered portion connected to the lower end of the throat, and a plurality of fuel gas supply ports provided in the tapered portion. The throat and tapered portion are coaxial with the axial center line of the lance.
