    摘要: A stacked body is formed by stacking a plurality of power generation cells in a stacking direction. End power generation cells are provided at opposite ends of the stacked body in the stacking direction. Each of the power generation cells includes a membrane electrode assembly and first and second metal separators sandwiching the membrane electrode assembly therebetween. The end power generation cells include first outer separators and second outer separators. The first outer separators are more highly hydrophilic in comparison with the first and second metal separators of the power generation cells.

    摘要: The present invention relates to a fuel cell separator and a method of producing the fuel cell separator. A first separator and a second separator are provided as the fuel cell separators. Firstly, the first separator and the second separator are heated. Thus, an Fe rich layer is formed in a surface layer of each of the first separator and the second separator, and a Cr rich layer where a proportion of Cr is 60% or more is formed in an inner portion of each of the first separator and the second separator. Then, an electrolytic treatment is applied to each of the first separator and the second separator to remove the Fe rich layer. By the removal, the Cr rich layer is exposed to the outside on the outermost surface layer of each of the first separator and the second separator.

    摘要: An adhesive suitable for solid polymer fuel cells is provided that has sufficient bond durability, so that the solid polymer electrolyte membrane and the gas diffusion layer do not separate, even with the solid polymer electrolyte fuel cell repeatedly wetting and drying, and changing in dimension. An adhesive including a base compound, a cross-linking agent, an adhesion promoting agent, and a reaction catalyst is employed using a specific base compound having alkenyl groups, and a specific cross-linking agent having Si—H groups, in which the ratio of moles of the above Si—H group relative to moles of the above alkenyl group (moles of Si—H group/moles of alkenyl group) is adjusted to the range of 1.0 to 5.0.
