▎ 摘　　要

NOVELTY - Apparatus comprises a diaphragm-less electrolytic cells comprising an anode and a cathode, where the anode comprise an anode cells in series, and the cathode comprises a 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. There are more anode cells in series than there are cathode cells in series, where a gap between the cathode and the solution electrode is greater than a gap between the anode electrode and the solution electrode. The electrodes are made of mesh or plate copper sparged with fine particles of Hastelloy c-276. The electrodes are made of mesh or plate graphene sparged with fine particles of Hastelloy c-276. USE - The apparatus is useful for electrolysing seawater. ADVANTAGE - The apparatus provides increased production of hydrogen from seawater, achieves higher capacity, and increases the cell voltage. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a membrane type Unipolar electrolytic cell; and a process for electrolyzing seawater.
