A new method for manufacturing anode supported solid oxide fuel cells with AFL

Abstract

In this study, two new methods are proposed for manufacturing anode-supported tubular SOFCs (solid oxide fuel cells) with AFL (anode functional layer). The anode supports are manufactured via thermoplastic extrusion. PEG is used as a secondary binder in the anode tubes and it is selectively removed by water debinding and sweat debinding methods and an AFL layer is obtained with different microstructure and porosity. The Sweat debinding method is suggested as a new method for forming an alternative layer with a different microstructure than the main body of the anode support. Full cells are produced from the altered anode supports. The peak power densities of the cells are measured as 0.38 W/cm2 for Sweat Debound cells, while it is 0.29 W/cm2 for the Water Debound cells.
