Abstract

The invention relates to the technical field of fuel cells, and provides a transfer process and a membrane electrode. The transfer process comprises the following steps: isopropyl alcohol and water are mixed as a solvent, perfluorosulfonic acid resin is added and then the mixture is uniformly mixed to prepare a perfluorosulfonic acid resin solution; the perfluorosulfonic acid resin solution is sprayed on aproton exchange membrane; the base material sprayed with the catalyst is placed on the two sides of the proton exchange membrane and hot pressing is performed; and the base material is stripped and thus the membrane electrode is obtained. Good adhesion is formed between the perfluorosulfonic acid resin and the original proton exchange membrane and the catalytic layer, and the proton exchange membrane and the catalytic layer are bonded by the perfluorosulfonic acid resin so that temperature and pressure required for transferring are greatly reduced while the high transfer rate is ensured, and the proton exchange membrane is protected from being damaged at high temperature and high pressure.

Description

Technical field [0001] The invention relates to the technical field of fuel cells, in particular to a transfer process of membrane electrodes. Background technique [0002] A fuel cell is an electrochemical cell that directly converts the chemical energy in fuel and oxidant into electrical energy through a redox reaction. Proton exchange membrane fuel cell (PEMFC) is an important branch of the fuel cell field. In addition to the general characteristics of fuel cells such as high energy conversion efficiency and environmental friendliness, it also has fast startup speed at room temperature, small size, and electroless Outstanding advantages such as liquid loss, easy drainage, long life, high specific power and specific energy. Proton exchange membrane fuel cell is not only suitable for the construction of decentralized power stations, but also suitable for mobile power supply. It is a new type of military and civilian mobile power sources. Therefore, proton exchange membrane fue...
