A three-dimensional (3D) fibrous cathode of solid oxide fuel cell was fabricated by using eggshell membranes (ESMs) as the template. This cathode possesses high porosity and interconnectivity, and low polarization resistance. A single fuel cell with the 3D fibrous Sm0.5Sr0.5CoO3/Ce0.8Sm0.2O1.9 cathode shows significantly improved performances at low operating temperatures (500-600 degrees C) as compared with the cell prepared with the ESM-templated cluster cathode in our previous study.
