Structural remodeling of Ni-based anodes for solid oxide fuel cells via static magnetic field

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.
