A pair of heat and pressure rolls, a fuel cell catalyst layer continuous transfer roll press device, a fuel cell membrane-electrode assembly (MEA) produced by the fuel cell catalyst layer continuous transfer roll press device, and the fuel cell Manufacturing method of fuel cell membrane-electrode assembly (MEA) using catalyst layer continuous transfer roll press apparatus

摘要

PPROBLEM TO BE SOLVED: To always carry out transcription with a uniform surface pressure, by carrying out a surface pressure adjustment with a pair of heating and pressing rolls, in a catalyst layer continuous transcription roll press device for a fuel cell, having the pair of heating and pressing rolls in which the catalyst layer is transcribed to the surface of a solid polymer electrolyte membrane. PSOLUTION: Of the pair of heating and pressing rolls, used in the catalyst layer continuous transcription roll press device for the fuel cell, having a pair of heating and pressing rolls for transcribing the catalyst layer to the surface of the solid polymer electrolyte membrane, by pinching the solid polymer electrolyte membrane and a catalyst layer carrying base material that has the catalyst layer formed on the surface, at least either is the heating and pressing roll (embossing roll) with a transcription part, having a roll state body part and a protruding state transcription part (embossed part) formed on the outer peripheral part of the body part, and a dummy protruding part for adjusting the face pressure is installed on the surface of the heating and pressing roll with the transcription part.
