Low Cost Green Hydrogen Production via Neutral Water Electrolysis and Polymer Cathode
This technology is a system for efficient and fast production of hydrogen by electrolysis of neutral water. This capability is in strong contrast to current systems, which operate with either highly acidic electrolytes or highly caustic media and require expensive or rare materials for the cathode. It is a cost-efficient and sustainable alternative...
