Stable overall water splitting in an asymmetric acid/alkaline electrolyzer comprising a bipolar membrane sandwiched by bifunctional cobalt‐nickel phosphide nanowire electrodes

Carbon Energy, 2020
Water splitting has been proposed to be a promising approach to producing clean hydrogen fuel. The two half‐reactions of water splitting, that is, the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), take place kinetically fast in ...

Analysis of the effect of surface wettability on hydrogen evolution reaction in water electrolysis using micro-patterned electrodes

Electrochemistry Communications, 2019
The hydrogen evolution reaction (HER) was investigated using Ni catalytic electrodes with micro-patterned surfaces. The present aim was to correlate HER efficiency with the surface wettability of Ni cathodes produced with different micropatterns. Regular

Advanced alkaline water electrolysis. Task 2 summary report. Model for alkaline water electrolysis systems [PDF]

, 1980
Task 2 involved the establishment of an engineering and economic model for the evaluation of various options in water electrolysis. The mode, verification of the specific coding and four case studies are described. The model was tested by evaluation of a nearly commercial technology, i.e., an 80-kW alkaline electrolyte system, operating at 60/sup 0/C ...

Coupling heat and electricity sources to intermediate temperature steam electrolysis [PDF]

, 2012
The use of CO2-free energy sources for running SOEC (solid-oxide electrolysis cell) technologies has a great potential to reduce the carbon dioxide emissions compared to fossil fuel based technologies for hydrogen production.

Ionic Transport Aspects of Water Electrolysis in Alkaline Media

Research
Water electrolysis is a key industrial process for producing green hydrogen. To avoid the use of noble metals and fluorinated polymer membranes, liquid water electrolysis is often carried out in alkaline conditions.

A high-performance capillary-fed electrolysis cell promises more cost-competitive renewable hydrogen

Nature Communications, 2022
Renewable, or green, hydrogen will play a critical role in the decarbonisation of hard-to-abate sectors and will therefore be important in limiting global warming. However, renewable hydrogen is not cost-competitive with fossil fuels, due to the moderate
