Advanced Commercial Electrolysis of Seawater to Produce Hydrogen

Abstract

An apparatus for electrolysing seawater is disclosed. In one embodiment, the apparatus includes diaphragm-less electrolytic cells including an anode and a cathode. The anode includes a plurality of anode cells in series and the cathode includes a plurality of cathode cells in series to control the cell voltage and substantially prevent the production of oxygen and chlorine in the cells while hydrogen is being produced. Also disclosed is a membrane type Unipolar electrolytic cell when used to process alkaline seawater to produce twice the hydrogen and oxygen compared to a conventional electrolysis of seawater.
