Bubbles in Porous Electrodes for Alkaline Water Electrolysis
Langmuir, 2023Porous electrodes with high specific surface areas have been commonly employed for alkaline water electrolysis. The gas bubbles generated in electrodes due to water electrolysis, however, can screen the reaction sites and hinder reactant transport, thereby deteriorating the performance of electrodes.

Abstract Among the catalysts for hydrogen evolution reaction (HER) in alkaline media, Ni–Mo turns out to be the most active one. Conventional preparations of Ni–Mo electrode involve repeated spraying of dilute solutions of precursors onto the electrode substrate, which is time-consuming and usually results in cracking and brittle electrodes.

Solid-State Water Electrolysis with an Alkaline Membrane
Journal of the American Chemical Society, 2012We report high-performance, durable alkaline membrane water electrolysis in a solid-state cell. An anion exchange membrane (AEM) and catalyst layer ionomer for hydroxide ion conduction were used without the addition of liquid electrolyte. At 50 °C, an AEM electrolysis cell using iridium oxide as the anode catalyst and Pt black as the cathode catalyst ...

Developments on IME-alkaline water electrolysis
International Journal of Hydrogen Energy, 1983Abstract A research programme aiming at the development of a new advanced concept in alkaline water electrolysis has been demonstrated at S.C.K.-C.E.N. under the auspices of the Commission of the European Communities. The first R&D task was the development of an alkali-compatible ion exchange membrane as a replacement of the chrysotile asbestos ...

Study of Alkaline Water Electrolysis (II)
ECS Transactions, 2013There are four main factors in the Alkaline Water Electrolysis (AWE) for contributing to the cell performance. One is cell structure which is related to the uniform electrolyte concentration with proper internal circulation of electrolyte in the cell room or the out gassing from electrode, separator and cell chamber.

Development of Membranes for Alkaline Water Electrolysis
ECS Meeting Abstracts, 2023Alkaline water electrolysis is one of the important methods for generating high purity hydrogen. Alkaline electrolysis, because of the possibility of using relatively inexpensive electrode materials, is more economical than hydrolysis in acidic medium; the medium is also less corrosive.

Electrodes for Alkaline Water Electrolysis
Journal of The Electrochemical Society, 1981Electrodes for alkaline water electrolysis have been made by applying high specific surface area coatings of nickel or nickel‐iron alloy to steel or nickel substrates. The coatings are applied as polysilicate‐based paints containing particles of the desired metals. The coating is sintered into a porous structure which is bonded firmly to the substrate.
