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.

Polymer electrolyte water electrolysis: Understanding the microstructure of a core-shell based anode catalyst layer

Reducing precious metal loading in the anodic catalyst layer (CL) is indispensable for lowering capital costs and enabling the widespread adoption of polymer electrolyte water electrolysis (PEWE). This work presents the first three-dimensional reconstruction of a TiO2-supported IrO2 based core shell catalyst layer, using high-resolution X-ray ptychographic tomography at cryogenic temperature of 90 K. The high data quality and phase sensitivity of the technique have allowed the reconstruction of all four phases namely pore space, IrO2, TiO2 support matrix and the ionomer network, the latter of which has proven to be a challenge in the past.

LEC Contribution to the SCCER Mobility Project

Two groups from the Electrochemistry Laboratory, together with a team from ZHAW and EPFL have developed a novel evaporative cooling concept for polymer electrolyte fuel cells from the material to the cell level.

The 5 min movie explains and summarizes the development.
