Polymer Electrolyte Membrane (PEM) electrolysis was initially conceived by Grubb in 1950s and developed in 1966 by General Electric [42]. In a typical PEM system, a solid polymeric membrane is used as an electrolyte instead of liquid [38,43].

PEM water electrolysers (PEMWEs) can achieve high current densities of up to 10.0 A cm −2 [12], but are mostly used up to around 2.0 A cm −2 [10]. This, and the use of a thin membrane, allows for a very compact design and a significantly reduced gas crossover compared to alkaline electrolysis.
