摘要： A separator for a fuel cell, to be disposed opposing to a membrane electrode assembly, is provided. The separator includes a separator central area portion opposing to a center area of the membrane electrode assembly that concerns generating power, an outer edge portion located in an outer edge of the separator central area portion, a rubber molded body made of rubber, the rubber molded body being formed in the outer edge portion by die-casting a die-casting rubber material using die, and an adhesive layer formed in the outer edge portion, for adhering the rubber molded body to the outer edge portion. The adhesive layer is formed over an adhesive layer area that includes and is larger than an area where the rubber molded body is die-casted in the outer edge portion. Thus, a disadvantage due to burrs which are generated when die-casting the rubber molded body can be reduced.

摘要： A terminal plate 160F is configured such that an electrically conductive aluminum core plate 181 having a current collector terminal 161 is placed between a titanium cell-side plate 182 and a titanium end plate-side plate 183 both having higher corrosion resistance. Both the cell-side plate 182 and the end plate-side plate 183 have plate outer peripheries extended more outward than the outer periphery of the core plate 181. A plate adhesive seal member 184 is arranged to cover the outer peripheries of the respective plates including the core plate 181 and keep the plate-sandwiched state. The core plate 181 has a gold-plated outer peripheral end face and is thereby in the non-bonded state with the plate adhesive seal member 184 on the outer peripheral end face.

摘要： In order to reduce corrosion of metal plates of a current collector which is comprised of the stacked metal plates made of different materials, a current collector for a fuel cell is provided, which includes a first metal plate that has a terminal portion and is conductive, and a second metal plate and a third metal plate that are metal plates having a higher corrosion resistance than the first metal plate and pinch the first metal plate therebetween. The current collector includes a first through-hole penetrating the first metal plate, the second metal plate, and the third metal plate, wherein fluid exists in at least either one of between the first metal plate and the second metal plate, and between the first metal plate and the third metal plate, and the first through-hole guides the fluid outside the current collector, and a first seal member blocking an end face of a perimeter of the current collector. A hole wall surface of the first through-hole is not blocked.

摘要： A separator for fuel cell is used for a fuel cell and is placed to face a membrane electrode assembly. The separator includes a separator center area placed to face a power generation area of the membrane electrode assembly; a peripheral region extended from the separator center area toward an outer edge; a cooling medium supply manifold and a cooling medium discharge manifold provided in the peripheral region; a fluid flow path area extended from the cooling medium supply manifold through the separator center area to the cooling medium discharge manifold; a sealing gasket provided in the peripheral region and placed to surround the fluid flow path area; and a gasket for peel test provided outside of the fluid flow path area and configured to receive an external force applied as a test for evaluation of an adhesive state of the gasket. Evaluating the adhesive state of the gasket for peel test improves the yield of products in manufacture of the separators for fuel cell.

摘要： A fuel-cell unit cell comprises an MEGA plate with a resin frame, and two separators. There is formed a gas manifold hole in an outer edge portion of the resin frame. There is provided a gas-flow-path forming portion with a recessed-and-protruded shape on the first surface of the resin frame for forming gas flow paths between the gas manifold hole and the first surface of the MEGA. There is also formed a fusion-bonding portion for surrounding a periphery of the gas manifold hole to cut off gas circulation between the gas manifold hole and the second surface of the MEGA and for bonding the resin frame and the second separator with each other, on the second surface of the resin frame so as to pass across a backside of the gas-flow-path forming portion. The fusion-bonding portion is formed from a first resin, and the gas-flow-path forming portion is formed from a second resin higher in melting point than the first resin.

摘要： In order to suppress an increase in electric resistance when retrieving electric power collected from a fuel cell stack, a current collector for a fuel cell is provided. The current collector includes a current collecting portion for collecting electric power generated by the fuel cell, and a terminal portion for outputting the power collected by the current collecting portion. A bus bar is attached to the terminal portion. The terminal portion includes a terminal portion main body, electrically connected with the current collecting portion, a first threaded part fixed to the terminal portion main body, a second threaded part for threadedly engaging with the first threaded part to fix one end of the bus bar to the terminal portion, and a protruded portion provided in the same surface as a surface where the first threaded part of the terminal portion main body is provided. The protruded portion is disposed at a position where the protruded portion contacts the bus bar to stop a rotation of the terminal portion main body accompanying fastening of the second threaded part, when the one end of the bus bar is fixed to the terminal portion in a state where the other end of the bus bar is fixed to another instrument.
