NOVELTY - Assembling plate type membrane electrode assembly layer comprises providing membrane electrode assembly (12), providing frame, providing bonding sheet (14), placing membrane electrode assemblies into first holes on frame, covering these membrane electrode assemblies with bonding sheet, and pressing the pressing areas so the bonding sheet, membrane electrode assemblies, and frame stacked sequentially could be joined as plate-type membrane electrode assembly layer where pressing areas are corresponding to outer periphery surrounding anodes and cathodes of the membrane electrode assemblies.    USE - The method is useful for assembling plate type membrane electrode assembly layer for use in fuel cell, particularly in direct methanol fuel cell (claimed).    ADVANTAGE - The method provides improved assembly quality for fuel cell and uses automated method to assemble and manufacture fuel cell in mass production. The method eliminates errors caused by human factors. The method reduces the problem of membrane electrode assembly in prior art for possible drying and easy to be curled. The method can use thermal press machine for one-time press forming without the manual assembly method to achieve the automation and mass production purpose and improves assembly quality for fuel cell.    DETAILED DESCRIPTION - Assembling plate type membrane electrode assembly layer comprises providing membrane electrode assembly, providing frame, providing bonding sheet, placing membrane electrode assemblies into the first holes (100) on the frame, covering these membrane electrode assemblies with bonding sheet, and pressing the pressing areas so the bonding sheet, membrane electrode assemblies, and frame stacked sequentially could be joined as plate-type membrane electrode assembly layer where the pressing areas are corresponding to the outer periphery surrounding anodes and cathodes of the membrane electrode assemblies. The frame is provided with first hole(s). The opening area of the first hole is smaller than the area of the membrane electrode assembly. The bonding sheet is provided with second hole(s) (140). The opening area of the second hole is slightly smaller than the area of the membrane electrode area. Each second hole corresponds to each first hole, respectively. The bonding sheet has pressing area(s) surrounding the second hole. The applying of pressing is carried out using thermal press machine (16). The frame is anode or cathode electrode board. The bonding sheet is Prepreg resin sheet or AB glue. An INDEPENDENT CLAIM is included for plate type membrane electrode assembly layer structure.
