PEM electrolyzers, for instance, rely on costly platinum group metals (PGMs ... effective materials in the production of green hydrogen to be used in water electrolysis." The study is published in the ...
Typically, electrolyzers follow one of two approaches: proton-exchange membrane (PEM) or alkaline electrolysis. The former tends to be pricier but more efficient, while the latter is less ...
While proton exchange membrane (PEM) and alkaline water electrolyzers (AWEs) are available, they face limitations in either cost or efficiency. PEM electrolyzers, for instance, rely on costly ...
