Welcome to the Electrochemistry Laboratory (LEC)
The Electrochemistry Laboratory (LEC), established 1988, is part of the Energy and Environment Research Division (ENE) at the Paul Scherrer Institute. The laboratory comprises 6 interacting research groups that deal with almost all aspects of electrochemical energy storage and conversion. PSI’s Electrochemistry Laboratory is Switzerland’s largest Center for Electrochemical Research.

Scientific Highlight
Towards Next Generation Membranes for Polymer Electrolyte Water Electrolysis
The conversion efficiency for green hydrogen production in a polymer electrolyte water electrolyzer (PEWE) is strongly influenced by the ohmic cell resistance and therefore the thickness of the membrane. The use of thin membranes (~50 micron or below) is limited by gas crossover of H2 and O2, which can lead to the formation of an explosive gas mixture. The incorporation of a Pt recombination catalyst provides remedy and allows a more dynamic operating mode (cf. Highlight 03/2022). However, the presence of Pt nanoparticles leads to an increase in the rate of membrane degradation. Therefore, we have additionally doped the membrane with cerium-zirconium-oxide (CZO) nanoparticles, which act as radical scavenger. The rate of membrane degradation can thus be reduced.
