N2 - 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 °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 H2 and atmospheric oxygen, produced maximum power densities of 420 W m-2 and 800 W m-2 at 450 °C and 550 °C, respectively.
