    摘要: Provided is a manufacturing method of a fuel-cell single cell including a membrane-electrode assembly, an anode gas diffusion layer, a cathode gas diffusion layer, and a frame-shaped resin frame to which a peripheral edge portion of the membrane-electrode assembly is fixed. The method includes an adhesive application step of applying an adhesive by screen printing to a predetermined area of the resin frame while fixing the resin frame by suction, and a stacking step and a UV irradiation step of bonding together the resin frame to which the adhesive has been applied and the membrane-electrode assembly by the adhesive.

    摘要: A fuel cell stack includes a cell stack body including a plurality of stacked power generation cells together. A metal plate and an elastic seal member are overlapped with each other at a position facing a bead seal formed on an end metal separator. A support member includes a recess accommodating the metal plate. A gap is provided between an inner peripheral end of the metal plate and the recess, or between an outer peripheral end of the metal plate and the recess, for absorbing thermal expansion difference between the metal plate and the support member.

    摘要: The present disclosure is directed to a bipolar plate of an electrochemical cell. The bipolar plate may have a frame and a base. The bipolar plate may also have a polymeric coating applied to at least one of the frame and the base. The present disclosure is also directed to a method of assembling a bipolar plate for an electrochemical cell. The method may include compressing a frame and a base of the bipolar plate, at least one of the frame and the base has a polymeric coating. The polymeric coating may be an electrical insulator for the electrochemical cell, a seal for sealing one or more zones of the electrochemical cell, and a corrosion protection later of the electrochemical cell.

    摘要: A gasket has a gasket main body which is made of a rubber-like elastic body, and a reinforcement body which is made of a material having a higher rigidity than the gasket main body. The gasket main body integrally has a tabular base portion, and a seal portion which is provided in an end portion in a width direction of the base portion, the reinforcement body is formed into a tabular shape, is set its thickness to be smaller than a thickness of the base portion, and is buried in the base portion in such a manner as to be exposed to a surface with one surface in a thickness direction of the base portion, and the reinforcement body is provided with a positioning hole for positioning the reinforcement body in relation to a metal mold forming the gasket main body on a plane.

    摘要: A method is for producing seals on faces of electrochemical reactor components intended to be stacked in order to form an electrochemical reactor Each component is in the form of a plate and having a first face and an opposing second face. The first face is designed to receive a first seal and the second face is designed to receive a second seal. The method includes shaping the first seals on the first faces of the components, the first seals being at least partially polymerized; depositing the second seals on the second face of the components; and shaping the second seals by compressing a stack formed from the components alternating with molding plates. Each molding plate has a bearing face pressed against the first face of a component and includes a groove designed to receive, without deforming, the first seal previously formed on the first face of said component, and a molding face pressed against the second face of another component and having a molding surface for shaping the second seal deposited on the second face of said other component as a result of compressing the stack. The method also includes at least partially polymerizing the second seals.
