I know this will sound stupid but...

I guess this topic is closed then. Thanks

use stranded wire.

google for buck converter schematic

The simple solution is to buy the hydrogen at your nearest hydrogen store.

Because of a fundamental thermodynamic property called "exergy", electrolysis is utterly and totally useless for bulk hydrogen energy production.

See

That will increase his AVAILBLE current, but will not change the current that his electrolysis cell draws -- in fact it will REDUCE it !! (fixed resistance.. lower voltage = lower current)

IF he used a buck converter.. say to drop the voltage to 2 volts (just above the electrolysis threshold), he would need 6 cells to to draw the same amount of POWER that he was consuming at the higher voltage.. he can get the same effect by putting 6 cells in series without the buck converter... either way he needs more electolysis cells -- putting them in series better utilizies the battery without the added headache of using a buck converter and putting the cells in parallel

You increase the current by decreasing the resistance of the circuit.

With plain water and two electrodes, typically some ionic compound is dissolved in the water; in one case I saw them use H2SO4 (conc. battery acid), but only a drop or two. Sometimes kids doing their first experiment use ordinary table salt, but the chloride screws up the results.

With just plain water and a little H2SO4, we'd produce maybe a liter or two in an hour.

But higher voltage will not make the water electrolyze faster - the molecules have a certain voltage where they'll split; any more voltage is just wasted.

Do you intend to make "free hydrogen" to run your car with? One thing to keep in mind is that you will never, ever get as much energy back as you had to put in in the first place.

Good Luck! Rich

I read on one site -- 3.55wk per cubic meter recoverable energy from the hydrogen (recovery method not specified ?? fuel cell ?? engine ?? turbine ??) vs approx 4.0kw/cu-meter to create the gas.. so 12% conversion losses
