Developments in advanced alkaline water electrolysis

International Journal of Hydrogen Energy, 1984
Abstract Two parallel alkaline water electrolysis programs are underway at the Noranda Research Centre. One of these is part of Canada's contribution to the International Energy Agency (IEA) hydrogen program. Its objective is the evaluation of new anode, cathode and separator materials on an industrially-significant scale.

Alkaline Water Electrolysis Anode Materials

Journal of The Electrochemical Society, 1985
Mise au point. On note que les meilleurs electrocatalyseurs sont des oxydes metalliques mixtes, surtout des spinelles AB 2 O 4 ou des perovskites ABO ...

Electrodes for Alkaline Water Electrolysis

Journal of The Electrochemical Society, 1981
Electrodes 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.

Noble fabrication of Ni–Mo cathode for alkaline water electrolysis and alkaline polymer electrolyte water electrolysis

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.

Low Cost Electrodes for Alkaline Water Electrolysis

ECS Meeting Abstracts, 2022
To succeed with the green transition, one must have cheap and reliable ways to store intermittent renewable energy. It is believed that hydrogen will play a key role in this regard, preferably through electrochemical water splitting. Alkaline water electrolysis is a mature technology, using nickel materials in most key components. Although Ni and Ni-

Solid-State Water Electrolysis with an Alkaline Membrane

Journal of the American Chemical Society, 2012
We 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 ...

Behaviour of oxygen bubbles during alkaline water electrolysis

International Journal of Heat and Mass Transfer, 1982
Growth rate, departure radius and population of oxygen bubbles at the transparent anode during alkaline water electrolysis have been investigated experimentally. The supersaturation of dissolved oxygen in the electrolyte adjacent to the anode surface has been derived from bubble growth rates. Ambient pressure (2–70 kPa) and molarity of the electrolyte (

(Invited) Alkaline Water Electrolysis Vs. PEM Water Electrolysis - Exploring Their Full Performance

ECS Meeting Abstracts, 2015
The future of energy conversion and storage is expected to rely on the production and storage of hydrogen via water electrolysis1. In this scenario, water electrolyzers will play a key role to the establishment of an energy matrix based on renewable but intermittent power sources (e.g. wind turbines and photovoltaics).

Ceramic diaphragms for advanced alkaline water electrolysis

Journal of Applied Electrochemistry, 1989
Chemically stable and physically strong, but relatively expensive diaphragms with low electrical surface-specific resistance have been developed for alkaline water electrolysis intended to work at temperature around and above 120°C at increased current densities and yet reduced cell voltage.

High efficiency water electrolysis in alkaline solution

International Journal of Hydrogen Energy, 1978
Abstract Methods of increasing the efficiency and lowering the capital cost of state-of-the art pressure-type electrolyzers are briefly reviewed. A doubling of current density, accompanied by a halving of the internal resistance, and improved electrode activity are required.
