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

14 January 2021
Conversion efficiency based on the higher heating value (HHV) of hydrogen for the electrochemical water splitting reaction.

Efficient Water Electrolysis at Elevated Temperature using Commercial Cell Components

Decarbonization of the energy system across different sectors using power-to-X concepts relies heavily on the availability of low-cost hydrogen produced from renewable power by water electrolysis. Polymer electrolyte water electrolysis (PEWE) is a promising technology for hydrogen (and oxygen) production for distributed as a well as centralized operation. The total cost of hydrogen is dominated by the electricity cost. Therefore, increase of conversion efficiency is pivotal in improving the commercial viability of electrolytically produced hydrogen. In this study, we investigate the prospects of improving conversion efficiency by reducing the membrane thickness from 200 to 50 micron and increasing the cell temperature from 60 to 120°C.

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.
