Use of microtubular design in solid oxide fuel cells is considered to be ideal for small power application up to kW scale since it has shown to have high thermal shock resistance and high electrode area per volume, resulting in high volumetric power density. In this study, using a form of microtubular, NiO-Fe2 O3 based material has been used as an anode material and investigated the microstructure and the fuel cell performance.
