摘要： The object of the present invention is to provide a fuel cell including a cell that is formed by sandwiching a 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, humidity is controlled 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： The hydrogen absorbing alloy electrode for alkaline storage batteries according to the invention is characterized in that a hydrogen absorbing alloy powder prepared by grinding a strip of hydrogen absorbing alloy produced by solidifying a molten alloy by the roll method and having a specified mean thickness to a specified mean particle size is used as a hydrogen absorbing material. In the process of producing this hydrogen absorbing alloy electrode in accordance with the invention, the above-mentioned strip of hydrogen absorbing alloy produced by the roll method is subjected to surface treatment prior to grinding.
The hydrogen absorbing alloy electrode of this invention features an improved high-rate discharge characteristic at low temperature. Moreover, since the activity of the roll and free sides of the strip of hydrogen absorbing alloy can be enhanced without sacrificing the hydrogen absorbing capacity, a hydrogen absorbing alloy electrode with a large capacity and an improved high-rate discharge characteristic at low temperature can be provided.

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.
