Solid oxide fuel cells(SOFCs) directly convert the fuel gases to electric energy through electrochemical reactions. The advantage of SOFCs is that they easily operate with diversified fuels such as natural gases owing to their high temperature operation. However, high temperature operation also incurs the challenge in enhancing long term reliability and durability of SOFCs. The most commonly used anode material is Ni/YSZ. This has, however, some drawbacks in terms of long-term reliability at high temperatures, hydrocarbon fuel usages, and so on, therefore the need to develop the new anode materials increases. This article summarizes the trend of the novel anode materials development of SOFCs.
