Hi,
I'm playing around with electrolysis and i've built a small hydrogen and oxygen gas generator. At first, i filled it up with a saturated salt and water solution (i know baking soda is better but i had no more). I touched it to a 12v lead-acid battery and got quite a big spark. Even in this short time, my 20 awg wires got pretty hot but i could see some bubbles that had been generated so i knew there wasn't a short. To fix this way to low resistance, i replaced my salt and water solution with just water. This time i hooked it up to 2 12v batteries in series and measured a current of about 6amps, which dropped down to 2-3amps after a few minutes. This means that at the start, the power was 144w but despite this, i couldn't see a lot of bubbles being generated. Also, my stainless steel electrodes started oxidizing, they discoloured to black and at the water surface, some kind of a yellow-brown-greenish foam started forming..
Any ideas?
Regards,
Cecemel
