Abstract:

Alloy nanoparticles(NPs)have been widely used in the anodes of solid oxide fuel cells (SOFCs) because of their excellent catalytic performances and high resistances to coke deposition and H2S. These unique properties mainly originate from the synergistic effect between different metals. In-situ preparation of NPs from parent oxides in reducing atmosphere can produce supported metal nanoparticles with high stability and parent oxides with high oxygen vacancies, which improves the electronic and ionic conductivities of anodes. The excellent catalytic performance of alloy catalysts makes it possible for SOFCs to take hydrocarbon as fuel and operate stably and durably. The trends and advances in metal alloy nanoparticles applied to the anodes of SOFCs are summarized and the prospects for further studies in this field are proposed.

Key words: solid oxide fuel cell, metal alloy nanoparticle, hydrocarbon, anode, catalyst, synergetic effect, perovskite
