A device that uses a porous, fluorine-rich membrane to separate seawater from a concentrated potassium hydroxide electrolyte solution, enabling direct hydrogen production from saltwater.

A process to produce green hydrogen directly from seawater using renewable electricity.

Another previous approach attempted to improve seawater electrolysis efficiency, but proved impractical for large-scale application.

A hydrogen production device that splits saltwater directly using a fluorine-rich porous membrane to separate seawater from a concentrated potassium hydroxide electrolyte solution. The device overcomes corrosion and side-reaction problems inherent in traditional seawater electrolysis and has demonstrated operational durability exceeding 3,200 hours.
