Abstract
Abstract An electrolysis apparatus and method including means for decomposing an electrolyte into one or more gas products, and also including means responsive to the pressure or flow condition of one of the product gases for controlling the electrical input to the electrolysis cell whereby to match the gas generation rate and the gas demand rate in the electrolysis system. Electrical power cost of the electrolysis process, a major operating expense, will be reduced if the gas generation rate responds to the demand rate.
