    摘要： A proton-conductive composite electrolyte membrane, for a fuel cell, comprises a metal-oxide hydrate with proton conductivity and organic macromolecules in which an intermediate layer is formed between the metal-oxide hydrate and the first organic macromolecular electrolyte. The intermediate layer can enhance the adhesion at an interface between the metal-oxide hydrate and the organic macromolecule, and thereby the amount of methanol that penetrates along the interface can be reduced. Accordingly, the composite electrolyte membrane has both high proton conductivity and low methanol permeability, and a membrane electrode assembly that comprises the composite electrolyte membrane can produce a high output.

    摘要： The device for electrochemically manufacturing an organic hydride of the present invention is characterized by the electrode structure thereof being a structure that forms a matrix in which a metal-catalyst supporting carbon or a metal catalyst is suitably intermingled with a proton-conductive solid polymer electrolyte as catalyst layers, and the catalyst layers are formed on the front and back of a proton-conductive solid polymer electrolyte membrane on which a layer that blocks water from passing through is formed. When water or water vapor is supplied to the anode side of this electrode and a substance to be hydrogenated is supplied to the cathode side, application of a voltage between the anode and the cathode causes an electrolysis reaction to the water to occur at the anode and a hydrogenation reaction to the substance to be hydrogenated to occur at the cathode, producing the organic hydride.

    摘要： When using a measurement of a crossover current density by the Gotesfeld method or a measurement of a methanol permeation coefficient by gas chromatography or by liquid chromatography, a measure for crossover amount may be given but the interrelation with a crossover loss is not clearly known and thus, it could not be possible to evaluate a degree of the crossover loss. The present invention has for its object the provision of a novel measuring method that is able to measure a methanol crossover loss directly.The measuring method is characterized by measuring a crossover loss of MEA for methanol fuel cell from a difference between a voltage when a cathode catalyst layer is not influenced by methanol crossover and a voltage when the cathode catalyst layer is influenced by the methanol crossover.

    摘要翻译： 当通过Gotesfeld方法测量交叉电流密度或通过气相色谱法或通过液相色谱法测量甲醇渗透系数时，可以给出交叉量的度量，但是与交叉损失的相互关系不清楚，因此 ，不可能评估交叉损失的程度。 本发明的目的是提供一种能够直接测量甲醇交叉损失的新型测量方法。 该测量方法的特征在于，当阴极催化剂层不受甲醇交叉影响的电压与阴极催化剂层受甲醇交换影响时的电压之间的差异，测量甲醇燃料电池的MEA的交叉损耗。

    摘要： A PEFC (polymer electrolyte fuel cell) has a cathode separator for a PEFC working at 100° C. or higher. The cathode separator has gas passages to fed oxidant gas. Each of the passages increases the sectional area thereof with going down stream along with gas flow. That is, the PEFC has the cathode separator whose passage is configured that the downstream side sectional area thereof is larger than the upstream side sectional area thereof. In addition, the area of contact between the rib surface of the anode separator and a diffusion layer of an anode is larger than the area of contact between the rib surface of the cathode separator and a diffusion layer of the cathode.
