The article discusses the innovative development of metal-supported reversible protonic ceramic cells (MS-rPCC) as a solution to challenges faced by solid oxide cells (SOCs). These cells operate efficiently in both fuel cell and electrolysis modes for power generation and hydrogen production. The research, led by a team at Huazhong University of Science and Technology, introduces pure nickel as a support structure, eliminating diffusion and reaction issues associated with conventional materials. An engineered transition layer addresses thermal expansion coefficient mismatch, enhancing cell stability and performance. The fabricated cell demonstrates improved power density and current density, with outstanding stability during operation and thermal cycling. Further research will focus on optimizing air electrode materials for enhanced performance at lower temperatures. The study, published in the Journal of Advanced Ceramics, showcases a significant step towards the commercialization of MS-rPCC technology, supported by funding from various Chinese research programs.
