simple OU proof

Do you know off hand, where I could access some data on that ?   

In the book "Hydrogen Production: by Electrolysis" by Agata Godula-Jopek but I saw pressure vs. efficiency curves in another paper.

Depending on voltage, electrolysis can be endothermic or exothermic, so precise voltage control is important, too.
Temperature is another important factor. Any water temperature increase due to the electric current flow represents wasted energy.
Besides the obvious potential energy of the HHO bubbles buoyancy, the absorption of heat from the surrounding water as the bubbles rise in it, decompress and cool down (as any decompressing gas does) represents another flow of energy - heat energy transfer from water to HHO bubbles. Note the direction of this transfer.
