Abstract Solid oxide fuel cell (SOFC) has been popular as an alternative method for generating electricity from hydrocarbon fuels like methane. This article critically evaluates carbon deposition problem encountered by hydrocarbon fuelled SOFC, carbon detection method and recent progress in the applications of cermet material as anode to mitigate the carbon deposition. Recently researchers have diverged from using conventional Ni-YSZ cermet material to alloying metals such as Ni, Cu, Zn, Fe, Co, Mo, Sn, W and Sb, coupled with ceramic oxygen conductors like doped zirconia, doped ceria, and perovskite-related materials such as doped promethium barium manganite (PBMO). Due to their reforming catalytic ability, Pt group metals gave outstanding carbon deposition tolerance, while Ni, Co and Fe alloys often result in carbon deposition. Single and alloy of metals yield different tolerance level such as those of Ni-ceramic and Ni-M-ceramic (M = metal). Fabrication methods are crucial in producing alloy. For example, despite of being non-reducible by hydrogen, certain metal oxides such as Zn in Ni Zn is reducible in alloy form, while other like Co are not. For future direction, we recommend both alloying and combining the ceramic component with mixing oxygen carrier that contain perovskite to enhance the carbon deposition tolerance of SOFC.

直接利用碳氢燃料的固体氧化物燃料电池金属陶瓷阳极研究进展：综述

摘要 固体氧化物燃料电池 (SOFC) 已成为一种从甲烷等碳氢燃料发电的替代方法。本文批判性地评估了碳氢燃料 SOFC 遇到的积碳问题、碳检测方法以及金属陶瓷材料作为阳极以减轻积碳的应用的最新进展。最近，研究人员已经从使用传统的 Ni-YSZ 金属陶瓷材料转向合金化金属，如 Ni、Cu、Zn、Fe、Co、Mo、Sn、W 和 Sb，再加上掺杂氧化锆、掺杂氧化铈和钙钛矿等陶瓷氧导体。相关材料，例如掺杂的钷锰钡 (PBMO)。由于其重整催化能力，Pt 族金属具有出色的碳沉积耐受性，而 Ni、Co 和 Fe 合金通常会导致碳沉积。金属的单一和合金产生不同的公差水平，例如镍陶瓷和镍锰陶瓷（M = 金属）。制造方法对于生产合金至关重要。例如，尽管不能被氢还原，某些金属氧化物如 Ni Zn 中的 Zn 可以合金形式还原，而其他像 Co 则不能。对于未来的方向，我们建议将陶瓷成分与含有钙钛矿的混合氧载体合金化和结合，以提高 SOFC 的碳沉积耐受性。
