Electrodes for potassium chloride electrolysis?

I am conducting an electrolysis experiment (fist time) that involves making potassium chlorate from potassium chloride in a concentrated 2-liter solution. I need a few pointers:

-What kind of electrodes can I use? Will two large pieces of stainless steel work? I have a tight budget and keep costs to a minimum.

-How much voltage/amperage should I use for a 2-liter solution? My car battery re-charger is capable of producing 12 volts and has a setting that allows either 2 or 10 amps.

-Is there any precautions or concerns that I need to know before conducting this experiment?

Thanks for the help!

You should not use stainless steel as an electrode for when conducting this electrolysis experiment. Instead, you should use carbon electrodes. Learn more about the experiment at

Thanks for the answer! Do you know of any store that sells carbon electrodes? Also, I have no intent on separating the salt into it's original elements--especially not chlorine gas, but I want to make sodium chlorate by adding oxygen atoms to the chlorine. It's widely known that electrolysis can produce potassium chlorate crystals, but I do not exactly know the chemistry behind it. Are oxygen molecules taken from the water?
