Abstract Developing low temperature solid oxide fuel cells has been a prerequisite for commercialization. In response to this issue, a novel strategy for the directional construction of Ni/SDC anodes via magnetic field to achieve better polarization than the traditional Ni/SDC anodes in low operating temperature range (≤600 °C) is exploited. In the condition of Ni and SDC particles lining up end to end to construct Ni/SDC anodes (Ni/SDC-BT), the polarization resistance (Rp) of the remodeled Ni/SDC-BT in humidified H2 are 0.263, 0.088 and 0.037 Ω cm2 at 500, 550 and 600 °C, respectively. Furthermore, the optimization mechanism is proposed via the microstructure model.

基于静磁场的固体氧化物燃料电池镍基阳极的结构重构

摘要 开发低温固体氧化物燃料电池是商业化的先决条件。针对这个问题，开发了一种通过磁场定向构建 Ni/SDC 阳极的新策略，以在低工作温度范围（≤600°C）下实现比传统 Ni/SDC 阳极更好的极化。在Ni和SDC颗粒首尾相连构建Ni/SDC阳极（Ni/SDC-BT）的条件下，改造后的Ni/SDC-BT在加湿H2中的极化电阻（Rp）分别为0.263、0.088和0.037 Ω cm2 分别为 500、550 和 600 °C。此外，通过微观结构模型提出了优化机制。
