ASSEMBLING METHOD USED FOR FLAT TYPE MEMBRANE ELECTRODE ASSEMBLY LAYER, AND ITS STRUCTURE

PROBLEM TO BE SOLVED: To provide an assembling method used for a flat type membrane electrode assembly layer and its structure. SOLUTION: This method used for the flat type membrane electrode assembly layer includes following steps. A step in which at least one or more membrane electrode assemblies are offered, a step in which a frame is offered, the frame is equipped with at least one or more first openings, and the opening area of the first opening is slightly smaller than the area of the membrane electrode assembly, a step in which a joining piece is provided, the joining piece is equipped with one or more second openings, the area of the second opening is slightly smaller than the area of the membrane electrode assembly, and the second openings each correspond to the first openings, a step in which the membrane electrode assemblies are each placed on the first openings of the frame, the joining piece covers the membrane electrode assembly, pressure-joining is applied to a pressurizing area surrounding each of the second openings on the joining piece, the joining section, each membrane electrode assembly, and the frame which are piled one by one are joined to form one flat type membrane electrode assembly layer structure, and each pressurizing area surrounds the membrane electrode assembly correspondingly to the outside periphery of the membrane electrode assembly.
