Description
Summary:Solid oxide fuel cells (SOFCs) are the most widely used fuel cells due to their excellent fuel flexibility, high efficiency and low emissions. Although the liquid fuels are easier to handle and transport than hydrogen, their direct use in SOFC leads to serious performance deterioration because of the coke formation on the traditional Ni‐based cermet anodes. In this review, the advances in the development of coking resistant anodes and the new liquid fuels such as oxygenated hydrocarbons to solve the problem of coke formation with Ni‐based anodes are summarized. It is concluded that Ni‐based cermets are still the most promising anode materials and some targeted modifications are needed to improve the coking resistance. Several strategies to improve the coking resistance of Ni‐based anodes are highlighted. The aim of this review is to provide some helpful guidance and potential directions for the future design of anodes for SOFCs utilizing liquid oxygenated hydrocarbon fuels directly. Solid oxide fuel cells (SOFCs) have attracted numerous attentions in the past decades due to their high fuel flexibility, efficiency and low emissions. Recent advances in the development of coking‐resistant SOFCs operating on liquid oxygenated hydrocarbons are reviewed with highlights in the design of highly active/stable anode materials and new liquid oxygenated hydrocarbon fuels.
