A method for producing a resin frame equipped membrane electrode assembly includes: a first conveyance step of supporting a sheet-shaped member having a cathode and an electrolyte membrane by a resin frame member to which the sheet-shaped member is joined and linearly conveying the supported sheet-shaped member to a pressure bonding device; a second conveyance step of conveying an anode to the pressure bonding device by way of a rotary table; and a pressure bonding step of heating and pressing the cathode and the anode from above and below by the pressure bonding device to thereby integrate the cathode and the anode together.

Method for producing resin frame equipped membrane electrode assembly

In a preparation process of a method for manufacturing a power generating cell stack, a stacking table provided with a vibratable stack guide portion projecting upward and a stack unit provided with a positioning portion guided by the stack guide portion are prepared. In the placing step, the stack unit is stacked on the stacking table by dropping the stack unit toward the stacking table while the positioning portion is stacked along the stack guide portion which is vibrated in the vertical direction.

Method and apparatus for manufacturing power generating cell stack body

A fuel cell stack includes a cell stack body, a stack case containing the cell stack body, and an end plate fixed to an end of the stack case. At least two recesses are provided at the end of the stack case, each of the recesses holding one end of each of positioning pins which position the stack case and the end plate. At least two positioning holes, into which the positioning pins are inserted, are provided in the end plate correspondingly to the at least two recesses.

Method and apparatus for producing resin frame equipped membrane electrode assembly

In a method of producing a membrane electrode assembly, a solid polymer electrolyte membrane and gas diffusion layers are stacked together in a stacking direction in a manner that electrode catalyst layers are interposed between at least parts of the solid polymer electrolyte membrane and the gas diffusion layers to form a stack body. A load is applied to the stack body in the stacking direction, and the temperature of the solid polymer electrolyte membrane is increased by high frequency dielectric heating. In this manner, the gas diffusion layers, the electrode catalyst layers, and the solid polymer electrolyte membrane are joined integrally to obtain the membrane electrode assembly.
