ntroduction to hydrogen production from PEM pure water：PEM water electrolysis technology is known as the development foreground of hydrogen production area is one of water electrolysis hydrogen production technology, it is compared with the traditional alkaline water electrolysis hydrogen production, PEM water electrolysis hydrogen production has good chemical stability, proton conductivity and gas separation of perfluorinated sulfonic proton exchange membrane replace asbestos as a solid electrolyte membrane, can effectively prevent the electron transfer, The advantages of improving the safety of electrolyzer include high gas output pressure, good purity, high current density, easy integration, simple system, and no need for extra auxiliary equipment, so it is simple to install, less maintenance and easy to operate.
