Decoupled Water Splitting for Green Hydrogen Production: Reshaping Water Electrolysis

Decoupled Water Splitting for Green Hydrogen Production: Reshaping Water Electrolysis

Green hydrogen production at scale is essential to fight global warming and climate change. The present water electrolysis technologies present significant barriers to meet this challenge, due to high system and operational costs that emerge from the need to divide each cell into gas-tight cathodic...
