Solid oxide fuel cells (SOFCs) are considered efficient green energy technology in the 21st century, but carbon deposition on Ni-based anodes is a common issue when hydrocarbons are used as fuel. On-cell reforming of hydrocarbons, also known as fuel pre reforming, is a promising solution for alleviating carbon deposition, by finding an efficient and stable fuel reforming catalyst such as perovskite oxides.
SOFC (solid oxide fuel cell, SOFC) is recognized to be efficient green energy technology in the 21st century. However, when hydrocarbons are directly used as fuel, carbon deposition is easy to occur in Ni-based anode, thus losing electrochemical catalytic activity. Fuel pre reforming is also called on-cell reforming of hydrocarbons, which has been a promising solution for alleviating the carbon deposition problem in cermet anodes to varying degrees. And the key factor is to find an efficient and stable fuel reforming catalyst. Perovskite oxides have stable structure, highly catalytic activity and adjustable thermal expansion coefficient for using on the cells, showing great potentials of application for fuel reforming. In this paper, we summarize the application of perovskite catalyst in CH4 fuel reforming based on the research of our group and other scholars, and puts forward the corresponding views and perspective, especially in perovskite catalyst with Ni exsolution.
