摘要： A unit cell that constitutes a fuel cell stack is obtained by sandwiching an electrolyte mem-brane/electrode structure with a cathode-side separator and an anode-side separator. A first resin member is provided along the entire periphery of the cathode-side separator in the outer peripheral portion of the cathode-side separator. Surfaces of the cathode-side separator are provided with sealing parts that cover a part of the first resin member and constitute a first sealing member.

摘要： A gasket manufacturing method is provided. The gasket has a base material with a bead and an elastomeric gasket body disposed in a top portion of the bead. The method includes sequentially forming the bead on one part of a plane of the base material and applying a molding material of the gasket body to the top of the bead. When forming the bead on the one part of the plane, a protrusion is formed in each end in the width direction in the top of the bead. The protrusions are utilized as a coating width defining means of the molding material when applying the molding material to the top of the bead.

摘要： The invention provides a method for manufacturing a substrate-integrated gasket, the method integrating a fiber substrate which is constructed by a pulp fiber having cellulose as a main component and a gasket body which is constructed by a rubber-like elastic body according to a rubber impregnation, wherein a plurality of substrate-integrated gaskets are obtained by executing an injection molding by plural stages of rubber metal molds. Further, the rubber material is filled in plural stages of metal mold cavities by passing the rubber material through the fiber substrate in which a rubber material flow channel in the metal mold is closed at its injection pressure. The invention can reduce a man hour for removing burr and cleaning a metal mold by suppressing generation of rubber burr at the molding time and can reduce an amount of disposal of a molding material, thereby achieving a good manufacturing efficiency.
