Review “Limitations of aqueous model systems in the stability assessment of electrocatalysts for oxygen reactions in fuel cell and electrolyzers” was selected as front cover in Current Opinion in Electrochemistry
17 November 2021
Cost and stability remain the greatest technical barriers to sustainably commercialize low-temperature fuel cells and electrolyzers. For tackling this problem, numerous advanced electrocatalysts have been proposed and tested in aqueous model systems. There are, however, increasing and evident concerns regarding the value of stability data coming from such studies.
Building a bridge between degradation studies in aqueous model systems and real-world systems as degradation is pronounced very differently in the two worlds. In their recent review titled “Limitations of aqueous model systems in the stability assessment of electrocatalysts for oxygen reactions in fuel cell and electrolyzers”, the three HI ERN-scientists Konrad Ehelebe, Dr. Daniel Escalera-López and Dr. Serhiy Cerevko give a short overview on the differences between the two systems and how they affect electrocatalyst degradation.
Thereby, they highlight several recent examples of how these effects were studied in the literature. Their review was recently published in Current Opinion in Electrochemistry and selected as front cover of the current issue. Submission of articles to Current Opinion in Electrochemistry is by invitation only.
