The PEM (proton exchange membrane) serves as the core component of the membrane electrode, not only conducting protons, isolating hydrogen and oxygen, but also providing support for the catalyst. Conventional electrolyzer membrane electrodes consist of a PEM (CCM) and a diffusion layer coated on both sides with cathode and anode catalysts, respectively. The PEM consumption is large, and the price of the PEM market is as high as ten thousand yuan per square meter, which severely restricts the commercialization process of the electrolytic cell.
