Abstract

Novel CGO/NiO-CGO dual-layer hollow fibres (HFs) have been fabricated in a single-step co-extrusion and co-sintering process. LSCF-CGO cathodes layers were then deposited onto the dual-layer HFs to construct micro-tubular SOFCs. The NiO in the micro-tubular HF-SOFCs was reduced at 550 degrees C using hydrogen gas to form Ni anodes. Scanning electron microscope images showed that the dual-layer HFs have porous anodes and dense electrolyte layers. Preliminary measurements with a HF-SOFC fed with H(2) and atmospheric oxygen, produced maximum power densities of 420 W m(-2) and 800 W m(-2) at 450 degrees C and 550 degrees C, respectively.
