Abstract: An electrical insulation mixture for forming a layer on a conductor surface is provided. The mixture includes an UV curable thermoset resin and a filler. The filler includes UV transparent platelets made of a platelet material. UV transparency is given for light in a wavelength range between 300 and 420 nm. Furthermore, a method for electrically insulating a metallic conductor is provided. The method includes obtaining the electrical insulation mixture, forming a jacketing on a surface of the metallic conductor using the mixture thus obtained, and exposing the mixture to ultraviolet radiation to cure the mixture, thus forming, from the jacketing, an electrical insulation layer on the surface of the metallic conductor. A metallic conductor with an electrical insulation layer can be obtained by using the electrical insulation mixture.

Abstract: The invention relates to an alkaline electrolyzer arrangement for producing hydrogen gas. The arrangement includes a first alkaline electrolyzer unit and a second alkaline electrolyzer unit, each one of the first and second alkaline electrolyzer units including a first end plate, a second end plate and a plurality of electrolyzer cells forming a cell stack arranged between the first and second end plates. The alkaline electrolyzer arrangement further including a load bearing surface arranged between the first alkaline electrolyzer unit and the second alkaline electrolyzer unit such that the second alkaline electrolyzer unit is arranged vertically above the first alkaline electrolyzer unit and is supported by the load bearing surface.

Abstract: A method for operating a plurality of electrolyzer-stacks includes determining a concentration of impurities, which is originated by a second reaction gas electrochemically produced at a second electrode type of each of the electrolyzer-stacks, within a first gas stream; generating a trigger signal if the concentration of the impurities of the second reaction gas within the merged first reaction gas exceeds a specific second reaction gas level; identifying at least one electrolyzer-stack out of the plurality of electrolyzer-stacks, which is low performing in respect to excessively feeding second reaction gas impurities into the first gas stream, by measuring a current density of at least one electrolyzer-stack of the plurality of electrolyzer-stacks, if the trigger signal is generated.
