This study deals with the preparation and characterisation of catalyst-coated membranes for an alkaline water electrolysis process. For this purpose, a chloromethylated anion-selective block copolymer styrene-ethylene-butylene-styrene 1,4-diazabicyclo[2.2.2]octane functional groups was used both as polymer electrolyte membrane ionomer binder. Non-PGM catalysts (platinum group metals), specifica...

Electro-conversion of carbon dioxide (CO2) into valuable chemicals is an efficient method to deal with excessive CO2 in the atmosphere. However, undesirable reaction kinetics bulk solution strongly limit current density, and thus it incompetent market promotion. Flow cell technology provides insight uplifting density. As flow configuration, membrane electrode assembly (MEA) has been proposed pr...

Abstract In recent years, proton exchange membrane (PEM) fuel cells have regained worldwide attention from academia, industries, investors, and governments. The prospect of PEM has turned into reality, with cell vehicles successfully launched in the market. However, today’s remain less competitive than combustion engines batteries, primarily due to their high cost short lifetime, which are sign...

The use of Cs0.5H0.5PW12O40 insoluble salt as a superacid promoter in the catalyst layer of a polymer electrolyte membrane fuel cell (PEMFC) has been investigated. An increase of performance has been recorded at intermediate temperatures (110–130 °C) and under low relative humidity (R.H.). The promoter appears to mitigate the ionomer dry-out effects in the catalytic layer and produces an increa...
