Electrode and Electrolyte for HHO Cell

Best electrode for HHO Cell Hydrogen Generator

Plates

316L stainless steel. Works best with Pulse Width Modulation (PWM). PWM is needed to prevent the HHO cell from overheating. Best efficiency is optained when distance between the plates is 3-4 milimeters.

Bolts

Stainless steel bolts. Not recomended because the HHO Cell is overheating. Also when using bolts in your HHO Cell the current tends to go strait from Anode to Cathode, so you can't use inter plate system and the gas production is low.

Wire

Stainless steel wire. Thin wired electrodes in your HHO cell gives low gas production and is prone to corrosion. There are a few HHO Cell Constructions with wire. Low gas production.

Tubes

Stainless steel tubes. Depending on size and setup HHO cells with tubes works very good and you don't even need a PWM. Just fill it up with tap water. This HHO design is the most used.

water molecule. it is involved in HHO production through water electrolysis

Best Winter HHO Cell Hydrogen Generator. Keep Your Electrolyte From Freezing.

3 cups of rain water
1 cup of hydrogen peroxide
1 cup of isopropyl alcohol
3 table spoons soda
2 ounces vinegar

First mix rain water with soda and vinegar. The reaction will give up bubbles. Then add the rest and let it cool. Use this electrolyte in your HHO Cell.
