Julius' new paper was published in Nature Communications!
13 April 2021
Our new paper On the limitation in assessing the stability of oxygen evolution catalysts using aqueous model electrochemical cells was published today in Nature Communications. In this work, we tackle the discrepancy in the lifetimes of oxygen evolution reaction (OER) electrocatalysts between aqueous model systems (AMS), which are commonly employed in fundamental research and polymer electrolyte membrane based membrane electrode assemblies (MEA), which are state of the art in today's water electrolyzers.
With a newly developed setup, we present the first measurement of real dissolution rate in an MEA system. A striking difference in the stability of an iridium oxide catalyst in the MEA system was observed compared to our established scanning flow cell coupled to an inductively coupled plasma mass spectrometer (SFC-ICP-MS). Thus, a series of measurements in AMS was performed to search for the origins of this discrepancy.
Our results indicate two main contributors being responsible for the dissolution discrepancy—first, a general overestimation of the acidity of the conditions in the MEA. Second, iridium oxide stabilizes in the MEA system on longer timescales.
We expect our findings to lead to a better understanding of OER catalyst degradation and, subsequently, to better performing water electrolyzers.

New paper online: Pt dissolution in realistic fuel cell catalyst layers
15 January 2021
Our new work on Pt dissolution in realistic fuel cell catalyst layers was published in Angewandte Chemie. In this current work we present the first experimental approach to measure Pt dissolution in gas diffusion electrodes (GDE). Therefore we coupled our GDE half-cell setup with inductively coupled plasma mass spectrometry (ICPMS). With this, Pt dissolution in realistic catalyst layers and the transport of dissolved Pt species through Nafion membranes are evaluated directly.
We hereby observe that (i) specific Pt dissolution is increasing significantly with decreasing Pt loading, (ii) in comparison to experiments on aqueous model systems with flow cells, the measured dissolution in GDE experiments is considerably lower and, (iii) by adding a membrane onto the catalyst layer, Pt dissolution is reduced even further. All these phenomena can be attributed to the varying mass transport conditions of dissolved Pt species, influencing re-deposition and equilibrium potential. With the presented method we were also able to measure the diffusion coefficient of Pt species in Nafion, which can be of great importance when modelling fuel cell degradation.
