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: Separators of multiple types capable of supplying and diffusing fluids such as an anode gas, cathode gas and coolant uniformly are prepared and combined to construct a fuel cell stack. Such a cell stack (20) for fuel cells includes separators of at least two types (types CA, C, A, C, CW and AW) for anode gas and cathode gas. Each separator is such that a corrosion-resistance layer is formed on at least one face of a metal plate (30) and a fluid supply and diffusion layer for the corresponding gas is formed by an electrically conductive porous layer on the corrosion-resistant layer. The at least two separators are stacked so as to face each other with at least an electrolyte membrane and catalyst layers on both sides of the membrane (a new membrane electrode assembly N-MEA) being sandwiched between the fluid supply and diffusion layers of the separators.
