摘要： 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.

摘要： 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.

摘要： A fuel cell gas supply and diffusion layer includes a sheet-like porous body layer, and a plurality of gas passage grooves formed on one surface of the porous body layer in parallel and formed in a zigzag shape or a wave shape respectively. As viewed in a plan view, a first rectangular region where circumscribes one gas passage groove and a second rectangular region where circumscribes a gas passage groove adjacent to the one gas passage groove overlap along a region in contact each other. An overlapping region where the first rectangular region and the second rectangular region overlap exists at any depth position of the grooves. According to the fuel cell gas supply and diffusion layer, it is possible to increase a power generation efficiency of a fuel cell.
