Abstract

A solid oxide fuel cell (SOFC) is an energy conversion device, which directly converts chemical fuels (e.g., H₂, CO, and C_xH_y) into electricity and heat with high efficiency up to about 90 %. The main by-product CO₂ when hydrocarbons used as fuels can be sequestrated or subsequently chemically transformed into chemical fuels (e.g., CO) by electrolysis using renewable energy sources, such as solar and wind. The state-of-the-art nickel and yttria-stabilized zirconia (YSZ) composite (Ni-YSZ) anode is deactivated in the presence of ppm level of H₂S and forming coke in hydrocarbons at the operating temperature of SOFCs. Currently, mixed ion and electron conducting (MIEC) metal oxides are being considered as alternatives for Ni-YSZ anode in SOFCs. In this review, we report the recent development of MIEC metal oxides anodes for advanced SOFCs.
