Abstract: Provided is a hydrogen refining pressure-boosting device which is durable even in a high-pressure environment. This hydrogen refining pressure-boosting device produces, from a hydrogen-containing gas, a refined hydrogen gas having higher pressure and higher purity than the hydrogen-containing gas. The hydrogen refining pressure-boosting device is equipped with multiple stacked cell structures, and a pressing structure that applies tightening stress in the direction in which the cell structures are stacked. In this hydrogen refining pressure-boosting device the flow path surface of a cathode-side separator is sized so as to be contained on the inside of the flow path surface of an anode-side separator, in the direction of a plane parallel to a solid polymer electrolyte membrane.

Abstract: A cell includes: a membrane electrode assembly; and a pair of separators. The membrane electrode assembly includes a polymer electrolyte membrane, an anode catalyst layer on a first main surface of the polymer electrolyte membrane, and a cathode catalyst layer on a second main surface. The anode catalyst layer contains a first catalyst material having activity against a hydrogen oxidation reaction and a first electrically conductive material whose electrical resistance under a hydrogen atmosphere and under an oxygen atmosphere are different from each other. The cathode catalyst layer contains a second catalyst material having activity against an oxygen reduction reaction and a second electrically conductive material different from the first electrically conductive material. An electrical resistance of the cell when the anode catalyst layer is under oxygen atmosphere is more than twice the electrical resistance of the cell when the anode catalyst layer is under hydrogen atmosphere.

Abstract: A membrane-electrode assembly including a catalyst layer that includes a catalyst-supporting carrier in which a catalyst is supported on a carrier made of an inorganic oxide, and a highly hydrophobic substance having a higher degree of hydrophobicity than the inorganic oxide, the catalyst layer being formed on at least one surface of a polymer electrolyte membrane. It is preferable that, in the membrane-electrode assembly, the degree of hydrophobicity of the highly hydrophobic substance is from 0.5 vol % to 45 vol % at 25° C., the degree of hydrophobicity being defined as a concentration of methanol (vol %) when a light transmittance of a dispersion obtained by dispersing the highly hydrophobic substance in a mixed solution of water and methanol reaches 80%.
