the reported work is on the preparation and characterization of polyvinyl alcohol -g- polyacrylic acid (pva-g-paa)/ polybenzimidazole sulfone (pbis) cation exchange membrane used for the electro dialysis of sodium chloride solution. the polymer syrup has been prepared using the grafting method with the help of polyvinyl alcohol and polyacrylic acid in the presence of water solvent. the polymer ...

This paper reports the performance of nickel oxide based electrode in alkaline anion exchange membrane water electrolysis. The membrane used is polystyrene based alkaline membrane and the electrode used is Nickel as cathode and Nickel oxide as anode. The electrochemical activity of the Nickel oxide is high compared to uncoated electrode. The AWE membrane electrode gave high current density at 3...

Water-fed photo-electrolysis cells equipped with perfluorosulfonic acid (Nafion® 115) and quaternary ammonium-based (Fumatech® FAA3) ion exchange membranes as separator for hydrogen and oxygen evolution reactions were investigated. Protonic or anionic ionomer dispersions were deposited on the electrodes to extend the interface with the electrolyte. The photo-anode consisted of a large band-gap ...

Titanium-silicon alloys have been electrochemically extracted from the multi-component titanium compounds in molten calcium chloride electrolyte. Sintered pressed pellets of titanium-bearing compounds served as the cathode, and the electrochemical experiments were systematically carried out at 900 °C, 3.1 V and 1000 °C, 3.8 V using a graphite-based anode and an improved inert-oxygen-ion-conduct...

Anion exchange membrane (AEM) electrolysis aims to combine the benefits of alkaline electrolysis, such as stability cheap catalyst and advantages proton-exchange systems, like ability operate at differential pressure, fast dynamic response, low energy losses, higher current density. However, today, AEM is limited by AEMs exhibiting insufficient ionic conductivity well lower activity stability. ...

Decoupled Water Electrolysis In article number 2102057, Yuanyuan Ma, Jianping Yang and co-workers introduce a low-cost high-rate electrode with Grotthuss topochemistry as solid-state redox mediator to decouple the acid water electrolysis for hydrogen production without use of membrane. This decoupled system facilitates utilization renewable energies high-purity at different spaces times.

Freezing-cryosurgery, and electrolysis-electrochemical therapy (EChT), are two important minimally invasive surgery tissue ablation technologies. Despite major advantages they also have some disadvantages. Cryosurgery cannot induce cell death at high subzero freezing temperatures and requires multiple freeze thaw cycles, while EChT requires high concentrations of electrolytic products-which mak...

The fundamentals, standardization, innovative strategies, and future direction of low-temperature water electrolysis including alkaline (AWE), proton exchange membrane (PEMWE), anion (AEMWE) electrolyses are discussed.

Green hydrogen production, i.e., produced on a CO2-neutral basis through the electrolysis of water employing renewable electricity, has attracted increasing attention. The electricity required is generated from Renewable Energy Sources (RES), for example, wind energy, hydropower, or solar energy. Since neither process production nor end products H2 and O2 are harmful to environment, green clima...
