Abstract:
1. A solid oxide fuel cell comprising an inner electrode, a solid electrolyte, an outer electrode, and a porous support, the inner electrode being located between the outer electrode and the porous support, the electrolyte being located between the outer electrode and the inner electrode, wherein the solid electrolyte comprises lanthanum-gallate-based oxide doped with Sr and Mg, the porous support comprises forsterite, and the porous support has a Mg/Si molar ratio of 1.90 to 2.2, and an A-to-B ratio (A/B) of 0.0% to 9.0% wherein A denotes a maximum peak height which appears at a diffraction angle 2θ=26.5° to 27.0° and B denotes a maximum peak height which appears at 36.5° to 37.0° in a powder X-ray diffraction pattern obtained by using Cu-Kα radiation.
