Current efforts in the development of Proton Exchange Membrane Water Electrolysis (PEMWE) are driven by the ongoing energy transition and the need to phase out fossil fuels, to reduce dependence on other countries for energy supply. However, since this technology strongly relies on precious metals for their functioning, it is imperative to reduce their content while ensuring good performances. [...]

In polymer electrolyte membrane (PEM) water electrolysis the active material component is the membrane electrode assembly (MEA) consisting of a cathode and an anode catalyst layer (CL) coated on a proton conducting membrane. During large-scale MEA production critical process steps are the temperature treatment (tempering) of CLs and the CL decal transfer onto the membrane as they have a great impact on electrode conductivity, which is an important factor in MEA performance.
