Dioxide Materials Alkaline Water Electrolyzers With Sustainion® Membranes Show Record Performance

Operate at high currents: 1 A/cm2 at 1.8-1.9 V

No need for precious metals

Rapid turn on and turn off

Enables one to replace PEM electrolyzers with alkaline water electrolyzers and get similar performance

Buy membranes to try in your own electrolyzer

Sustainion® 37 membranes are the key to enabling alkaline water electrolyzers to operate at high currents

Sustainion® 37 membranes outperform the competition.
