Degradation mechanism and modeling study on reversible solid oxide cell in dual-mode d A review

Degradation issues are major obstacles to commercializing reversible solid oxide cells (rSOCs), which are promising energy production/storage devices. This article organizes and comprehensively reviews the current understanding of degradation issues in rSOCs, which range from fundamental research on degradation in both single and dual modes to solution strategies for both bifunctional material development and preparation/manufacture optimization, as well as modelling work performed at different scales to predict the degradation behaviours of rSOCs. It proposes perspectives for state-of-the-art work on degradation and solutions highlighted in reversible operation. An in-depth review of the links and differences for degradation in single and dual modes is also emphasized. The trade-offs between various degradation issues for rSOCs must be considered by further understanding the degradation mechanisms in dual-mode operation to improve the reversibility/ durability of long-term applications.(c) 2022 Hydrogen Energy Publications LLC.
