The best electrode material for the plates is 316L-grade stainless steel. It is hard to believe, but there is a voltage drop across the plate, which makes it necessary to apply about 2 volts to the plates on each side of the cell. So, if you are running off 12 volts, then six cells in a row across the battery gives the maximum possible drive. With the engine running and providing almost 14 volts, seven cells gives the highest possible drive. The electrolyte heating up is a wholly bad thing as it drives a good deal of water vapour out of the electrolyte and this mixes with the gas and is fed to the engine. Injecting water mist, which is a fine spray of water droplets, into an engine increases its performance due to the water expanding when it is heated. This improves both the engine power and the miles per gallon, and it makes the engine run cooler, which improves the life of the engine. But water vapour is a bad thing as it is already fully expanded and just gets in the way of the hydroxy gas, diluting it and lowering the power of the engine with no benefit at all. As the voltage applied to the cell is pretty much fixed, the current flow is controlled by the concentration of Potassium Hydroxide in the electrolyte and the plate area. Once the cell is built, the plate area is fixed, so the current is adjusted by controlling the amount of KOH added to the water. There is a slight limit to this, in that the gas production increases with KOH concentration until the concentration reaches 28% (by weight). After that point, any increase in the concentration produces a reduction in the rate of gas production. General practice is to have a fairly low concentration of KOH which is found by trial. Bob Boyce, who is very experienced in this field, says that you should never add water to NaOH or KOH. Always start with water, and add the chemical to the water SLOWLY, stirring well and allowing the mixture to cool in between additions. Shelf life depends on how well it is sealed from the atmosphere. Carbon is an enemy to this process. Whether the KOH is in dry or liquid form, it will absorb carbon from CO2 in the atmosphere, or any other source of free carbon. As this happens, the catalytic effect is diminished. The more carbon is absorbed, the less the catalytic efficiency of the electrolyte. So, if you wish to maintain maximum performance, it is crucial to keep air out of your dry or liquid chemical storage containers, AND away from the electrolyte in your cells.
