Abstract: The invention relates to water-electrolysis hydrogen production technology, in particular to electrolyte supply structure for providing uniform fluid flow for large alkaline hydrogen electrolyzers. The electrolyte supply structure includes a bipolar electrode frame that has an electrolyzer cell inside, an outlet located at the top, and three inlets (a first inlet, a second inlet, and a third inlet) located at the left, middle, and right of the bottom, wherein the third inlet having a barrier plate located at the left inside. This invention, by setting the three inlets replacing the original two inlets and adjusting the inlets' width, quantities, and inlets' angles, effectively increases the uniformity of fluid flow inside the cell, improves performance, and has no influence on mechanical processing and cost.

Abstract: The invention discloses a self-derivative iron-containing nickel anode for alkaline water electrolysis and its preparation method. The anode comprises a nickel substrate and catalytic material layer. The catalytic layer is disposed on and integrated with the surface of the nickel substrate. The catalytic layer contains nickel oxide with iron components. The nickel oxide results from the reaction of the surface layer of the nickel substrate with an oxidant-rich alkaline solution and forms a nanosheet array layer. A nickel-oxidation state containing the iron component is formed by electrochemically induced iron-ion corrosion of the nickel-oxidation state. The invention can effectively reduce the potential difference between the anode and cathode of an electrolysis cell, thereby significantly reduces energy consumption and improves the efficiency of water electrolysis.
