Abstract This project will advance the technical and commercial readiness of solid oxide electrolysis cells (SOECs) by developing protective coatings and Cr-getters to enhance system life. An integrated degradation mitigation strategy consisting of SOEC optimized interconnect (IC) coating, Cr-getters, and a balance-of-plant (BoP) coating consisting of a surface pretreatment to roughen the metal surface and promote the adhesion of a functional overlay coating will address the critical degradation mechanisms of metal corrosion and chromium evolution. These degradation mechanisms are substantial and mitigation strategies are essential to improve SOEC durability and achieve the DOE performance and lifetime targets for SOEC systems.
