This study aims to investigate the fabrication of anode/electrolyte dual-layer hollow fiber (DLHF) with improved electrolyte properties and reduced sintering temperature for intermediate temperature solid oxide fuel cells (IT-SOFCs) via a single-step phase inversion-based co-extrusion/co-sintering technique. The sintering properties of cerium gadolinium oxide (CGO) electrolyte were studied by comparing two approaches: i) using mixed particle size electrolyte; and (ii) adding lithium oxide as sintering additive in electrolyte. When comparing the maximum power density of MT-SOFC namely nickel (Ni)-CGO/CGO (unmodified), Ni-CGO/30%nano-70%micron CGO (first approach) and Ni-CGO/lithium (Li)-CGO (second approach); it was found that the Ni-CGO/30%nano-70%micron CGO cell performed the best. At 500 °C, the cell produced the highest maximum power density, which was 27.5 mWcm−2 as compared to …
