In our previous discussions, we analyzed the fundamental differences between alkaline (ALK) and proton exchange membrane (PEM) electrolysis, particularly focusing on the types of electrolytes used—liquid for ALK and solid for PEM. Given the century-long development of water electrolysis technology, why has PEM consistently attracted the attention… Read More

Proton exchange membrane (PEM) water electrolysis technology (PEMEL) is one of the more mature water electrolysis hydrogen production solutions in the current industrial and research fields.1. Working principle of PEM electrolyzerThe PEM electrolyzer uses electricity to decompose water into hydrogen and oxygen. The core process is as follows:1. Wat… Read More
