The electrolysis of water using a source of renewable energy is the key technology for carbon-free hydrogen production. However, PEM water electrolysis was considered as most promising techniques for high pure efficient hydrogen production and emits only oxygen as byproduct without any carbon emissions. Titanium-based electrodes coated with iridium catalyst are presently recognized as the top anode electrodes in PEM electrolyzers, which exhibit superior electrochemical activity for the hydrogen evolution reaction(HER) in acidic electrolytes. As a leading manufacturer of anodes and electrodes, YUXI’s titanium electrodes are the best option for optimizing output and life.
