Anode Materials for All-Perovskite Fuel Cells

Some materials can match some requirements, but it is very hard to find a material that can match all the stringent requirements for SOFC anodes, particularly redox stability and conductivity. Materials with perovskite structure are promising, such as the redox stable anode (Lao.75Sro,25)Cro.5Mno.503 [54] and Sr2MgMoOg [58]. These materials exhibit performance approaching that of the traditional Ni-YSZ anode. Therefore, we can use a nickel-free redox-stable anode for SOFCs. With further optimization of the composition and microstructure, the performance of these materials may be further improved and hopefully replace the traditional Ni-YSZ anode in the future. There have been a number of recent reviews including the topic of oxide anodes where further information may be obtained [67, 68]
