Industrial membrane of proton exchange membrane Industrial membrane of proton exchange membrane – Cheersonic Proton exchange membrane fuel cell (PEMFC) has the advantages of light weight, high efficiency, high specific power, high energy conversion rate, low starting temperature and environmental friendliness. It is an ideal power source for new energy vehicles and portable electronic products. Membrane electrode (MEA) is the core component of proton exchange membrane fuel cell, mainly composed of gas diffusion layer (GDL), catalytic layer (CL) and proton exchange membrane (PEM). Proton exchange membrane (PEM) is one of the core components of PEMFC, which can transfer protons but insulate electrons, which directly affects the performance and service life of fuel cells. A PEM with good performance must meet the following conditions: 1) Strong proton conductivity; 2) Good mechanical properties and not easy to deform; 3) High thermal and electrochemical stability. At present, the membra...
