The present invention provides an electrode for electrolysis in which electrolysis performance is hard to deteriorate and excellent catalytic activity is kept stable over a long period of time even when electric power in which there is a large fluctuation in output, such as renewable energy, is used as a power source. The electrode for electrolysis is an electrodefor electrolysis provided with an electrically conductive substrateat least the surface of which contains nickel or a nickel-based alloy, an intermediate layerformed on the surface of the electrically conductive substrateand containing a lithium-containing nickel oxide represented by composition formula LiNiO(0.02≤x≤0.5), and a catalyst layerof a nickel cobalt spinel oxide, an iridium oxide, or the like, the catalyst layerformed on the surface of the intermediate layer

Electrolysis electrode and method for manufacturing same

Provided are an anode for alkaline water electrolysis that can achieve a low overpotential at low cost, and a method for producing the anode for alkaline water electrolysis. An anode for alkaline water electrolysis having electrode catalyst layerscomposed of a first catalyst component having either a nickel-cobalt spinel oxide or a lanthanide-nickel-cobalt perovskite oxide and a second catalyst component having at least one of iridium oxide and ruthenium oxide formed on the surface of a conductive substratecomposed of nickel or a nickel-based alloy, and a method for producing the anode for alkaline water electrolysis.

Anode for alkaline water electrolysis and method for producing anode for alkaline water electrolysis

Provided is a water treatment system using an alkaline water electrolytic device and an alkaline fuel cell in which for continuing an electrolytic treatment, a hydrogen gas and an oxygen gas required in an alkaline water electrolytic device and an alkaline fuel cell, an amount of water corresponding to raw water lost through the electrolytic treatment, and an electrolytic solution are efficiently circulated and used in a water treatment system to considerably reduce electric power consumption. The water treatment system is a water treatment system using an alkaline water electrolytic device and an alkaline fuel cell in which an alkaline water electrolytic device and an alkaline fuel cell are connected to each other, the volume of raw water is reduced, an oxygen gas and a hydrogen gas that are generated from the alkaline water electrolytic device are fed to the alkaline fuel cell, the oxygen gas and hydrogen gas are used to generate electric power by the alkaline fuel cell, electric energy and water are collected, and the collected electric energy is fed to the alkaline water electrolytic device as an electric power source thereof.
