Abstract

Solid oxide fuel cells (SOFCs) are important electric generators due to their high energy efficiencies and fuel flexibilities. However, the high operation temperature (>800 °C) results in high system cost/complexity and poor long-term durability. Recently, decreasing the operating temperature of SOFCs to the low-temperature range (≤650 °C) has attracted intensive attention, especially for the direct utilization of hydrocarbons as fuels. This review summarizes the latest progress in hydrocarbon fueled SOFCs working at ≤ 650 °C, mainly focusing on the challenges and strategies associated with electrolytes, anodes, and cathodes. It highlights the requirement for highly active and carbon/sulfur resistant anode and high ionic conductive electrolytes to gain a superior performance at a lower temperature.
