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.

Alkaline Water Electrolysis Powered by Renewable Energy: A Review [PDF]
Processes, 2020 Alkaline water electrolysis is a key technology for large-scale hydrogen production powered by renewable energy. As conventional electrolyzers are designed for operation at fixed process conditions, the implementation of fluctuating and highly intermittent renewable energy is challenging.

Advanced alkaline water electrolysis
Electrochimica Acta, 2012A short review on the fundamental and technological issues relevant to water electrolysis in alkaline and proton exchange membrane (PEM) devices is given. Due to price and limited availability of the platinum group metal (PGM) catalysts they currently employ, PEM electrolyzers have scant possibilities of being employed in large-scale hydrogen ...

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 ...

International Journal of Hydrogen Energy, 2014
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.

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.
