Abstract

In this research, the performance of a tubular fuel cell based on a nickel oxide–yttria-stabilized zirconia (Ni-YSZ) anode support containing 90 wt% NiO ≈ 82 vol.% of Ni (Ni82) is compared with a cell containing the conventional Ni-YSZ support with 50 vol.% Ni. A Ni-YSZ buffer layer with a tailored microstructure was added to the Ni82 support layer to provide intermediate porosity and to reduce the thermal expansion mismatch with the anode functional layer. Both cells were tested using infiltrated Nd₂NiO_4+δ cathodes. High peak power densities of 790 and 478 mW/cm² were achieved at 600 and 550°C, respectively, for the Ni82 cell which was 25% and 87% higher than the performances for the conventional cell at respective temperatures. In addition, no degradation was found during four redox cycles at 550°C, making this support an attractive candidate for low-temperature solid oxide fuel cell applications.

为低温应用量身定制固体氧化物燃料电池阳极支撑成分和微观结构

在本研究中，将基于含有90wt%NiO≈82vol.%Ni（Ni82）的氧化镍-氧化钇稳定氧化锆（Ni‐YSZ）阳极载体的管状燃料电池的性能与含有50vol.%Ni的传统Ni‐YSZ载体的电池进行了比较。将具有定制微观结构的Ni‐YSZ缓冲层添加到Ni82支撑层中，以提供中等孔隙率并减少与阳极功能层的热膨胀失配。使用渗透Nd2NiO4+δ阴极对两种电池进行测试。Ni82电池在600°C和550°C时分别达到790和478 mW/cm2的高峰值功率密度，这比传统电池在各自温度下的性能分别高出25%和87%。此外，在550°C下的四次氧化还原循环中未发现降解，这使其成为低温固体氧化物燃料电池应用的一个有吸引力的候选者。
