A NEW METHOD FOR MANUFACTURING ANODE SUPPORTED SOLID OXIDE FUEL CELLS WITH AFL

In this study, a new method to manufacture anode supported SOFCs (solid oxide fuel cells) with AFL (anode functional layer) is proposed. To manufacture the anode supports, anode mixture with polyethylene glycol (PEG) is prepared and anode mixture is fed into a twin screw extruder and extruded in the shape of tubes. PEG in the anode tubes is selectively removed to by water debinding and sweat debinding methods and AFL layer is obtained with different microstructure and porosity. SEM (Scanning electron microscope) images of the manufactured SOFCs show AFL layers with the thickness of approximately 7 µm, which is akin to the values given in the literature. Electrolyte and cathode layers are added to the anode tubes using dip coating. Effects of AFL on performance of the manufactured cells are tested. © 2022 Proceedings of WHEC 2022 - 23rd World Hydrogen Energy Conference: Bridging Continents by H2. All rights reserved.
