Both a stoichiometric and a nominally A\u2010site deficient chromite anode material showed promising performance at 860\u2009\u00b0C approaching the ones of state\u2010of\u2010the\u2010art Ni\/Gd\u2010doped ceria (CGO) anodes. While the difference in polarization resistance was small, an increased ohmic resistance of the perovskite anodes was observed, which is related to their limited electronic conductivity. Increasing the chromite electrode thickness was shown to enhance performance and stability considerably. Degradation increased with current density, suggesting its dependency on the electrode potential, and could be reversed by redox cycling. Sulfur poisoning with 20\u2005ppm hydrogen sulfide led to rapid voltage drops for the chromite anodes. It is discussed that Ni nanoparticle exsolution facilitates hydrogen dissociation to the extent that it is not rate\u2010limiting at the investigated temperature unless an insufficiently thick electrode thickness is employed or sulfur impurities are present in the feed gas.<\/jats:p>","DOI":"10.1002\/cssc.202100330","type":"journal-article","created":{"date-parts":[[2021,4,12]],"date-time":"2021-04-12T15:54:50Z","timestamp":1618242890000},"page":"2401-2413","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Performance and Limitations of Nickel\u2010Doped Chromite Anodes in Electrolyte\u2010Supported Solid Oxide Fuel Cells"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0383-2545","authenticated-orcid":false,"given":"Matthias","family":"Riegraf","sequence":"first","affiliation":[{"name":"Institute of Engineering Thermodynamics German Aerospace Center (DLR)  Pfaffenwaldring 38\u201340 70569 Stuttgart Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diana M.","family":"Amaya\u2010Due\u00f1as","sequence":"additional","affiliation":[{"name":"Institute of Engineering Thermodynamics German Aerospace Center (DLR)  Pfaffenwaldring 38\u201340 70569 Stuttgart Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noriko","family":"Sata","sequence":"additional","affiliation":[{"name":"Institute of Engineering Thermodynamics German Aerospace Center (DLR)  Pfaffenwaldring 38\u201340 70569 Stuttgart Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.
