    Abstract: In a polymer electrolyte fuel cell of the present invention, at least one of electrodes comprises conductive carbon carrying a platinum group metal catalyst, conductive carbon carrying no catalyst metal and a hydrogen ion-conductive polymer electrolyte. The preferable amount of the conductive carbon carrying no catalyst metal is equivalent to 5 to 50 wt% of the conductive carbon carrying the catalyst metal. Incorporation of the conductive carbon carrying no catalyst metal to the catalyst layer enables reduction in potential concentration on part of electron conduction channels in an electrode, whereby an electrode for a polymer electrolyte fuel cell having an excellent life characteristic can be provided.

    Abstract: The judgment about the freshness of food and drink has been made subjectively, and hence often not clear-cut; therefore, investigation has been actively made of the technology to use a semiconductor gas sensor to sense the freshness of food and drink. However, the gas sensors of the prior art have not been capable of sensing gases of, for example, ethylene, ethanol, aldehydes, mercaptans and amines, which are important in sensing the freshness of vegetables and fruits, with satisfactory responsiveness and excellent durability.
    The gas sensor of the present invention includes: an insulating substrate 1; a pair of thin film electrodes 2 provided on the insulating substrate 1 in such a manner as to leave a fixed space between them; a gas sensitive film 3 including a metallic oxide which is provided in such a manner as to substantially fill at least the fixed space left between the electrodes; and a catalytically active protective layer 5 formed in such a manner as to cover the surface of the metallic oxide exposed to the outside.

    Abstract: An object of the present invention is to provide a catalyst-coated membrane suitable for achieving a polymer electrolyte fuel cell that sufficiently prevents a decrease in the initial characteristics and also exhibits sufficient cell performance for a long period of time and has excellent durability. In at least the cathode catalyst layer, the ratio (W P /W Cat-C ) of the weight of the polymer electrolyte (W P ) to the weight of the catalyst-carrying carbon (W Cat-C ) is decreased from an innermost layer positioned closest to the polymer electrolyte membrane toward an outermost layer positioned farthest from the polymer electrolyte membrane. The ratio (W P /W Cat-C ) in the innermost layer is 0.8 to 3.0, and the ratio (W P /W Cat-C ) in the outermost layer is 0.2 to 0.6.

    Abstract: A polymer electrolyte fuel cell comprises a hydrogen-ion-conductive polymer electrolyte membrane, a pair of electrodes sandwiching the membrane, a conductive separator plate having a gas passage for supplying a fuel to one of the electrodes, and a conductive separator plate having a gas passage for supplying an oxidant to the other electrode. Conventionally, a conductive separator plate is made of a carbonaceous material, and therefore the costs such as the fabrication cost are difficult to reduce, and a metallic plate is used on trial instead of a carbonaceous plate. However the metallic plate is exposed to a hot oxidizing atmosphere, and as a result the metallic plate is corroded after a long use, lowering the power generation efficiency gradually. According to the invention, the metallic conductive separator plate is a type in which a conductive coat comprising conductive particles and glass is formed on a surface having a gas passage. Thus, the corrosion of the metallic plate is suppressed and the degradation of the power generation efficiency after long use is also suppressed.

    Abstract translation: 聚合物电解质燃料电池包括氢离子传导性聚合物电解质膜，夹着膜的一对电极，具有用于向一个电极供给燃料的气体通道的导电性隔板，以及具有气体的导电性隔板 用于向另一个电极供应氧化剂的通道。 通常，导电性隔板由碳质材料构成，因此难以降低制造成本等成本，在试制中使用金属板代替碳质板。 然而，金属板暴露于热氧化气氛，结果金属板在长时间使用后被腐蚀，逐渐降低发电效率。 根据本发明，金属导电隔板是在具有气体通道的表面上形成包含导电颗粒和玻璃的导电涂层的类型。 因此，抑制了金属板的腐蚀，并且也抑制了长时间使用后发电效率的劣化。
