| Sumario: | With the growing demand for green energy and environmentally friendly society, there is an urgent need to accelerate the development of advanced energy conversion devices or systems, and fuel cells are considered future efficient power generationen systems. Among different types of fuel cells, solid oxide fuel cells (SOFCs) are a kind of clean power generation devices with broad prospects due to their unique multi-fuel operation capability and high energy conversion efficiency. However, due to incomplete oxidation of the hydrocarbon fuels, the traditional nickel-cermet anodes used in SOFCs operating under hydrocarbon fuels results in carbon deposition on the anode, leading to a decrease in the cell performance. In this review, the carbon deposition mechanism and strategies to solve carburization in anode of hydrocarbon-fueled SOFC were discussed, mainly focusing on the widely studied various types and the research progress of bimetallic-cermet materials with mixed ion-electron conductors. The carbon resistance mechanism of bimetallic-cermet materials were summarized, mainly manifest in reducing the carbon deposition rate on the anode surface and accelerating the removal of carbon deposition. The principle of in situ exsolution of nanoparticles in perovskite materials under reducing atmosphere were introduced as well, the application of nanoparticles formed by in situ exsolution and metal oxide heterostructures formed with perovskite bodies in carbon-resistant anodes were discussed. In addition, the application of multilayer anodes and single-atom catalyst anodes in intermediate temperature SOFCs were explored. Driven by the tremendous progress of fuel cell technology, there has been a new interest in pursuing integrated coal gasification fuel cells (IGFCs) power generation systems that can be used as stationary power generation. This system is of great significance for achieving clean and efficient utilization of coal, and the key to this technology lies in the maturity of SOFCs. Finally, some future research directions in hydrocarbon-fueled SOFCs were proposed. © 2024 China International Book Trading Corp. (Guoji Shudian). All rights reserved. |
