Abstract
Aiming at designing a high performance cathode for solid oxide fuel cells (SOFC), orientation of the La2NiO4 (LNO) with layered structure was controlled by slip casing in a strong magnetic field. The oriented LNO compact along a,b-axes was successfully fabricated in a static magnetic field. The c-axis oriented one was managed by applying a rotating magnetic field perpendicular to the slip casting direction. Enhanced conductivities were valid along a,b-axes orientation which resulted in the accelerated mobility of conducive carriers. From those results, it is clearly expected that the orientation control of LNO brings about high performance in the cathode of SOFC.
