Abstract
Described herein are novel alumina substrate-supported thin film SOFCs that may be produced at significantly reduced cost while providing improved robustness, high electrochemical performance, and the capability of effective carbon deposition resistance while still using Ni-cermet as an anode functional layer.
Claims19
A micro-tubular solid oxide fuel cell comprising:
- a NiO-SDC anode substrate;
- an internal graphite layer;
- at least one micro channel forming a micro channel array extending through both the NiO-SDC anode and the internal graphite layer, wherein the internal graphite layer is removed to provide access to the at least one micro channel in the NiO-SDC anode substrate;
- an electrolyte outer coating;
- and
- at least one cathode ink applied to the electrolyte outer coating.

A method for making a micro-channel array structured micro-tubular solid oxide fuel cell comprising:
- employing at least one polymer binder, at least one solvent and at least one dispersant to prepare an organic solution;
- mixing at least two anode powders and introducing them to the organic solution to form an anode slurry;
- employing a graphite slurry as an inner layer of an anode substrate with the anode slurry forming an outer layer;
- employing an internal coagulant;
- employing a phase inversion based dual-layer co-extrusion process with respect to the graphite slurry, anode slurry and internal coagulant;
- solidifying the respective slurries to form at least one micro-tubular body;
- applying at least one electrolyte layer to the at least one micro-tubular body;
- and
- applying at least one cathode ink onto the at least one electrolyte layer.
