摘要： An anode for oxygen evolution in electrolytic processes comprising a nickel-based planar substrate having a first side and second side and a porous catalytic coating formed on at least one side of the substrate, wherein the porous catalytic coating exhibits a lamellar morphology made from metallic patches and void patches, the metallic patches being made from a material selected from nickel, nickel oxide, a nickel-aluminium alloy, or combinations thereof. The present invention also concerns a method for the production of such an anode using powder plasma spraying or electric wire-arc spraying.

摘要： The present invention relates to a system for direct detection of current supplied to the electrodes of electrolytic cells, particularly useful in non-ferrous metal electrowinning or electrorefining plants. The current distribution on a practically unlimited number of electrodes can be obtained through direct measurement on the electrode hanging bars without requiring the manual intervention of plant staff.

摘要： An electrolytic enrichment method for heavy water includes enriching heavy water by electrolysis using an alkaline water electrolysis cell including an anode chamber that holds an anode, a cathode chamber that holds a cathode, and a diaphragm. In the method, an electrolyte prepared by adding high-concentration alkaline water to raw material water containing heavy water is circularly supplied to the anode chamber and the cathode chamber from a circulation tank; an anode-side gas-liquid separator and an anode-side water-seal device are connected to the anode chamber, and a cathode-side gas-liquid separator and a cathode-side water-seal device are connected to the cathode chamber; and electrolysis is continued while the alkali concentration in the electrolyte supplied to both electrolysis chambers is maintained at a constant concentration by circularly supplying, to the circulation tank, the electrolyte from which the gas generated from the anode-side gas-liquid separator and the cathode-side gas-liquid separator is separated.
