Solid oxide fuel cell (SOFC) is a clean and efficient power generation device fed by hydrogen or hydrocarbon fuels. Liquid bio-fuel is a kind of renewable hydrocarbon fuel, which is produced by catalytic pyrolysis of biomass and further catalytic processing. It contains bio-methanol, bio-ethanol, bio-diesel and its by-product bio-glycerin, etc. It is portable, clean and efficient to use liquid bio-fuels for SOFC power generation. However, direct use of liquid bio-fuels will lead to the deactivation of SOFC anode carbon deposition. Thus, a reforming progress is necessary for long-term durability as well as high efficiency for power generation. The reforming progress of liquid bio-fuels was analyzed, including conversions and distributions of products for bio-methanol, bio-ethanol, bio-glycerin and bio-diesel, respectively. The research progress of liquid biomass fuel used in SOFC power generation was also summarized, and the future research direction of liquid biomass fuel used in SOFC was put forward, in order to improve the utilization efficiency and stability. © 2021, Chemical Industry Press Co., Ltd.
