A solid oxide fuel cell (SOFC) including a flat-tubular anode and a cathode. In an embodiment, the flat-tubular anode and the cathode can be substantially thick. In an embodiment, the cathode can have a coefficient of thermal expansion (CTE) that is substantially the same as a CTE of the flattubular anode. In an embodiment, the cathode can have channels formed within the cathode for the intake of air/oxygen from an outside source.
