Abstract

The invention discloses a novel sealing process of a fuel cell membrane electrode, and relates to the technical field of fuel cell membrane electrodes. The product quality is improved; a fuel cell membrane electrode of the process comprises a catalyst coating membrane, and the catalyst coating membrane is specifically a 3CCM composed of a proton exchange membrane, an anode catalyst layer and a cathode catalyst layer; a first polyester resin frame A and a second polyester resin frame A are arranged at the top and the bottom of the catalyst coating film respectively, a first polyester resin frame B is arranged at the top of the first polyester resin frame A, and a second polyester resin frame B is arranged at the bottom of the second polyester resin frame A; and a first gas diffusion layer is arranged at the top of the first polyester resin frame B. According to the invention, through a sealing process of'first frame and then gas diffusion layer ', accurate positioning of the polyester resin frame is realized by using the positioning holes. And precise positioning of the gas diffusion layer is realized by utilizing the inner edge of the polyester resin frame.

Description

technical field [0001] The invention relates to the technical field of fuel cell membrane electrodes, in particular to a novel sealing process for fuel cell membrane electrodes. Background technique [0002] A fuel cell is a device that directly converts the chemical energy of fuel into electrical energy. It has the advantages of high efficiency, no pollution, light weight, etc., and has great development potential and application prospects. Among them, the proton exchange membrane fuel cell can work at low temperature and has high power density, which is very attractive in application. Membrane electrode is the core component of proton exchange membrane fuel cell, and it is the place of energy conversion inside the fuel cell. The membrane electrode is responsible for the multiphase material transport in the fuel cell, and is responsible for converting the chemical energy of the fuel into electrical energy through electrochemical reactions. Among them, the sealing technolo...
