This week, I would like to highlight the paper by Xu et al., which reports a methodological study of liquid water distribution in gas diffusion layers of PEFC by using a synchrotron based operando X-ray tomographic microscopy (XTM). The authors were able to capture water dynamics in 4D by coupling ex-situ and in-situ XTM experiments. This method should be of interest to the community of fuel cells, electrolyzers, and batteries.

I also enjoyed reading Rob Darling’s theoretical paper on resistance of oxygen transport in air electrodes containing high surface area carbon (e.g. Ketjenblack). This work is an extension of his 2018 JES paper, which reported an analytical model for nanoscale transport resistance in air electrodes that contains low surface area carbon (e.g. Vulcan XC-72). His very recent JES paper was equally interesting which described a model to examine resistance of proton transport in catalyst layers with various Pt/C ratios. (Contact author: Robert M.

I would like to thank all of the reviewers for their diligent and continuing service to The Electrochemical Society, which made the following publications possible.
