The invention relates to the technical field of membrane
electrode production processes, and provides a process method for producing a membrane
electrode. The process method comprises a
thermal transfer printing process method, a thermal compounding process method, a
carbon paper laminating process method and a
hot pressing process method. The
thermal transfer printing process method comprises the following steps that S11,
thermal transfer printing is performed on a material A and a material B; and S12, the material A and the material B subjected to
heat transfer printing are rolled. The thermal compounding process method comprises the steps that S21, a material A subjected to thermal
transfer printing is
cut into sheets, and the sheets are transferred and pasted to the position above a lower frame material belt; and S22, an upper frame material belt is arranged above the material A subjected to
heat transfer printing, and a semi-finished product material belt is formed through heating and rolling. The
carbon paper laminating process method comprises the following steps: S31, respectively transferring and laminating
carbon paper above and below a semi-finished product material belt; and S32, heating, rolling and compounding, and
cutting into sheets. The hot-pressing process method comprises the following step of S41, carrying out
hot pressing on a
sheet material. Continuous automatic production of the membrane
electrode is realized, and the production efficiency and quality of the membrane electrode are improved.
