A positive voltage is applied to the electrode in the first tank and a negative voltage is applied to the electrode in the second tank. The two electrodes are electrically linked. Preferred Assembly: A series of such tanks are linked in series. The electrolyte is salt-enriched water that is broken down by electrolysis into hydrogen and oxygen. The salt is sodium chloride, hydrogen hexachlorioplatinate, potassium penta-chloroaquo-ruthenium. The electrolyte is dimethoxmethane or trimethoxymethane, trioxane, methanol, formaldehyde, formic acid or sulfuric acid with added water. One of the electrodes has a platinum coating.
