Postdoc position on the local analysis of structure and reactivity of membrane-electrode assembly for PEM water electrolysers

Proton Exchange Membrane Water Electrolyzer (PEMWE) is currently considered as a promising solution for hydrogen production from renewable energy sources. For economical interest and durable development, it is essential to study the mechanism of the degradation of PEMWE for predicting and improving its lifetime under practical operational conditions. One of the key factors affecting the durability of PEMWE is the heterogeneity, which arises from the materials as well as the operational conditions.

The ANR Multi-Hero project (Clarifying degradation causes in PEM water electrolyzers via multiscale Heterogeneity characterizations) aims to clarify the impact of multiscale heterogeneity on the degradation of a key PEMWE component, the membrane electrode assembly (MEA), by employing novel and in-operando characterization tools across multiple scales. The measurements will be realized before cell assembly, during the accelerated degradation test, and post-mortem after the test. The m...
