Reverse Osmosis Membranes

A relatively inexpensive commercially available RO membrane was shown to be useful for direct seawater H2 generation as the membrane can selectively transport protons and hydroxide ions over other salt ions, and keep the inert anolyte contained to avoid chlorine gas evolution.
