Novel electrolytic cell for producing hydrogen from water

The utility model relates to a novel water hydrogen production electrolytic cell which adopts a composite electrode and utilizes a capillary liquid absorption structure to supply liquid, the novel water hydrogen production electrolytic cell comprises a plurality of small electrolysis chambers, an end pressing plate, a pole frame, a sealing gasket and the like, and each small electrolysis chamber comprises a current collection gas separation plate, a porous metal gas channel layer, a composite cathode containing a catalyst layer, a capillary liquid absorption diaphragm, an anode and a liquid storage tank. The composite cathode for hydrogen evolution comprises a porous carrier layer and a catalyst layer. The surface of the porous carrier is roughened to form micropores, and the catalyst is arranged on the surface of the porous carrier. The water electrolyzer spontaneously sucks the electrolyte from the liquid storage tank for electrolysis by utilizing the capillary action through the capillary liquid suction di
