How can I bring the amps down on a electrolisis project

Question

with 12 volts and over 30 amps the temperatur go very hight

Answer 1

I hope this is not one of those HHO auto things. a total scam, it won't work.

Quit before you kill yourself.

but to get the amps down, use less salt in the water, or move the electrodes further apart, or use smaller electrodes.

Answer 2

Reducing the voltage would reduce the waste heat. Only around 2 volts are needed to split the water. I think the other 10v * 30A = 300 watts are mostly going into heating. Presumably this is one of those HHO things and you are using a car battery (and alternator which is taking more power from your engine that you will ever get from the HHO) so changing the voltage will be difficult, using a resistor simply moves the heat out side the cell, doing nothing for efficiency.

Bills suggestions will bring the amps down and reduce heating, but will also proportional reduce gas production, which would be undesirable if you have a legitimate use for the gas produced (but would be a big plus for a HHO car add on which isn't going to work anyway)

Putting multiple cells in series might be an option.

Answer 3

You know i hate to say this but that's 360watts of ,i guess DC power ...each watt represents 3.14 btu so you have about 1080 btu being produced. If that was funneled into you home via a coil and propane refrigerator you could save about 150dollars per year on one refrigerator.. and more on a load shed freezer application. Also the free hydrogen generator is a function of electron flow ..cut dow the amperage and you turn the output down. Also since the Resistance is a function of the cross sectional area of the conductor perhaps you need a lager filament...Basically reducing the Amperage in is reducing the mole of H out....Sorry but it take energy to break the bond...Not all answer are the ones you want to here huh...Havwe a good one from the E...

Answer 4

You could use a power source with less current capacity but higher voltage. Or you could use a current-limiting circuit, like a resistor placed in parallel to your electrolysis device.
