Thanks Jamie, I used 316L on mine, just a step above T304, but way more expensive and I don't think made a difference verses T304, so you should be good with T304. :D

Jeff, i think 316L is a good choice. I have no doubt it will give years of good service.

Well as I understand it the O2 forms on the anode and H2 on the cathode, so using it together with SS then, just to get a diode action going, I'm guessing it doesn't matter which is which in this case.
But why not try the Titanium as anode for starters.........?
As long as the diode forms, that's what I'd be aiming for anyway, the rest is still unwritten ;)

Has anyone tried coating their cathodes with a layer of graphene? But don't coat platinum with graphene... when exposed to hydrogen, the graphene reorganizes into diamond when it's on a platinum surface. And diamond isn't conductive.

Who wants to lay odds that some enterprising individual is, at this moment, working to generate molecularly flawless diamonds from plain old graphite via graphene / hydrogen interaction? No pressure or heat required, just keep adding graphene and hydrogen and let the crystal grow to whatever size you want. The reorganization is spontaneous and results in diamonds with no occlusions. We're at the advent of a world where we can literally generate whatever molecule we want. But I'd lay odds that diamonds still won't be cheap, no matter how easy it is to make them.

Perhaps he tried out phosphoric acid, propylene glycol, isopropanol, perhaps even dish soap...........? :angel:

I saw a YouTube video of a guy from Japan running his dissociation machine with dish soap. I'd discussed earlier about how the surface tension of water is caused by the hydrogen atoms attempting to glom on to anything around them (usually oxygen via intermolecular water molecule bonding), but at the surface there's only 180 degrees of material they can attach to, so the hydrogen molecules at the surface have stronger bonds intermolecularly, which hinders dissociation to some degree. The Japanese guy said dish soap broke up the surface tension, making it easier to dissociate the water.

Also, here's some info about a paper Pollack wrote, pertaining to water and capacitance at low and high voltages:
High electrical permittivity of ultrapure water at the water–platinum interface
