Product Description
water electrolysis is a mechanism that uses electricity to electrolyze water into oxygen and hydrogen.
There are three main types of water electrolysis devices: "polymer electrolyte membrane (PEM) water electrolysis", in which pure water passes through a solid polymer membrane with a catalyst, and reacts with the catalyst to decompose it into hydrogen and oxygen; "alkaline water electrolysis, in which an electric current is passed directly through a strongly alkaline solution to generate hydrogen and oxygen; and solid oxide electrolysis cell (SOEC) water electrolysis, in which water vapor is electrolyzed at high temperatures.
PEM water electrolysis hydrogen production uses perfluorosulfonic acid proton exchange membrane with good chemical stability, proton conductivity and gas separation as solid electrolyte instead of asbestos membrane, which can effectively prevent electron transfer and improve the safety of Electrolyzer. The main components of the PEM water electrolyzer are proton exchange membrane, cathode and anode catalytic layer, cathode and anode gas diffusion layer, cathode and anode end plates, etc. from inside to outside. Among them, the diffusion layer, the catalytic layer and the proton exchange membrane form the membrane electrode, which is the main place for the material transmission and electrochemical reaction of the entire water electrolyzer. The characteristics and structure of the membrane electrode directly affect the performance and life of the PEM water electrolyzer.
Hydrogen is considered a key solution for the energy transition and decarbonization of industry. It cannot be underestimated that we are experiencing the rapid maturation of a new global economy.As an energy carrier, hydrogen is both carbon-free and more energy-dense than natural gas.
