Abstract
Click to copy section linkSection link copied!
The increasing demand for sustainable energy solutions has driven interest in ceramic electrochemical cells, which are also known as solid oxide electrochemical cells, for high-efficiency power generation and hydrogen production. Ceramic electrochemical cells offer fuel flexibility and reduced CO2 emissions. However, high operating temperatures (>700 °C) result in higher costs and performance degradation. Efforts to lower the operating temperatures have led to advancements in materials, particularly Bi2O3-based ionic conductors, which are known for their superior oxygen ion conductivity. Despite their potential, Bi2O3-based materials suffer from instability at the expense of facile ionic transport. This review examines recent research addressing these challenges, focusing on intrinsic properties, chemical compositions, cell designs, and fabrication methods to improve the stability and performance. Additionally, the potential of incorporating Bi3+ into other oxides is explored. The discussion and summary in this review aim to guide the rational design of ceramic electrochemical cells operating at low temperatures with Bi2O3-based ionic conductors.
