Table salt supports electrodeless electrolysis in the presence of 13.56mhz EMF.

I could not tell how they would direct the oxygen one way and the hydrogen some other way.

Like with other "undirected" mechanisms, filtering membranes and liquification refining can be used to go from gaseous H2/O2 mix to separated H2

"More effective electrocatalysts screening strategies are needed to establish the standard evaluation protocol for effective comparisons of the performances of catalysts from different research groups. Nevertheless, the surge of recent interests in nanostructure and lattice oxygen engineering of catalysts is expected to lead to new advances in the design of active, stable, and low-cost OER and HER electrocatalysts for the mass commercialization of water-splitting based hydrogen production."

I wonder if we need something like the services NREL performs for solar cells - a standardized test suite that labs/companies can bring their research cells to be tested.
