I like your idea of just pushing a battery .3v past fully charged.
That's easy to do, uses little power, and can be controlled with
just one transistor and a pot. I'd use a coarse, granular or
spherical material, say copper BB's and lead shot or zinc pellets,
separated in either half of a container by any mesh material that
will stand up to acid, and leaving enough air-space for gas bubbles
to trickle upwards. As opposed to my earlier posts, why let the acid
attack the materials? Just over-drive the cell 24/7. Even when resting,
the H2 generating cell should have a fully charged battery preventing
it from discharging. What we need to know and be sure of however,
is that H2 production is from splitting water, not stripping the H2 from
H2SO4 as Orange_Crusader suggested in another discussion. My
gut hunch is that overdriving the cells is preferable and the easiest
way.
