Solid oxide fuel cells (SOFCs) that can operate on hydrocarbon fuels offer an efficient and cost-effective solution for electricity generation. However, broader commercialization of SOFCs is hindered by inadequate performance and limited durability due to the sluggish hydrocarbon reforming/oxidation kinetics and coking on the SOFC anode. Here it has been reported that these findings in design, synthesis, and characterization of a novel anode catalyst Ba(Zr_0.8Y_0.2)_0.9(Ni_0.5Ru_0.5)_0.1O_3-δ (BZYNR) that overcomes the problems, enabling direct utilization of nearly dry hydrocarbon fuels (e.g., methane, ethanol, and iso-octane with only 3 vol% H₂O) with exceptional power output for over 1000 h on both button cells and tubular cells. The outstanding performance of BZYNR is attributed to the high activity of hydrocarbon reforming and the accelerated water-mediated carbon cleaning process on Ni-based SOFC anode.

固体氧化物燃料电池以碳氢化合物燃料运行，具有出色的耐用性和功率输出

可以使用碳氢化合物燃料运行的固体氧化物燃料电池 (SOFC) 为发电提供了一种高效且具有成本效益的解决方案。然而，由于碳氢化合物重整/氧化动力学缓慢和 SOFC 阳极结焦，SOFC 的性能不足和耐久性有限，阻碍了 SOFC 的更广泛商业化。_{据报道，在新型阳极催化剂 Ba(Zr 0.8} Y _0.2 ) _0.9 (Ni _0.5 Ru _0.5 ) _0.1 O _3-δ (BZYNR)的设计、合成和表征中的这些发现克服了这些问题，实现了直接利用几乎干燥的碳氢化合物燃料（例如，甲烷、乙醇和仅含 3 vol% H _{2的异辛烷）}O) 在纽扣电池和管状电池上都具有超过 1000 小时的出色功率输出。BZYNR 的出色性能归因于碳氢化合物重整的高活性和镍基 SOFC 阳极上加速的水介导的碳清洁过程。
