The potential to use ethanol as a fuel places solid oxide fuel cells (SOFCs) as a sustainable technology for clean energy delivery because of the renewable features of ethanol versus hydrogen. In this work, we developed a new class of anode catalyst exemplified by Ni+BaZr0.4Ce0.4Y0.2O3 (Ni+BZCY) with a water storage capability to overcome the persistent problem of carbon deposition. Ni+BZCY performed very well in catalytic efficiency, water storage capability and coking resistance tests. A stable and high power output was well maintained with a peak power density of 750 mW cm(-2) at 750 °C. The SOFC with the new robust anode performed for seven days without any sign of performance decay, whereas SOFCs with conventional anodes failed in less than 2 h because of significant carbon deposition. Our findings indicate the potential applications of these water storage cermets as catalysts in hydrocarbon reforming and as anodes for SOFCs that operate directly on hydrocarbons.
乙醇作为燃料的潜力使固体氧化物燃料电池（SOFC）成为清洁能源输送的可持续技术，因为与氢气相比，乙醇具有可再生的特点。在这项工作中，我们开发了一类新型的阳极催化剂，以 Ni+BaZr0.4Ce0.4Y0.2O3（Ni+BZCY）为代表，具有储水能力，以克服积碳的持续问题。Ni+BZCY 在催化效率、储水能力和抗结焦测试中表现出色。在 750°C 时，峰值功率密度为 750 mW/cm²，可稳定维持高功率输出。具有新型坚固阳极的 SOFC 连续运行七天而没有任何性能下降的迹象，而使用传统阳极的 SOFC 则因为严重的积碳而在不到 2 小时内失效。我们的研究结果表明，这些储水金属陶瓷作为催化剂在烃类重整中的潜在应用以及作为直接在烃类上运行的 SOFC 的阳极。
