Development of Self-Supporting Air Electrode SOFC

The authors are studying a self-supporting SOFC using the spray coating method, etc. A high-performance self-supporting air electrode has successfully been produced by the extrusion-sintering method, and a cell with its electrolyte and fuel electrode manufactured by the plasma spray coating method on the air electrode proved to have good performance. The maximum output density of a single cell is 0.31W/cm{sup 2}. Furthermore, the authors are developing a FGM (Functionally Gradient Material) film as the fuel electrode produced by the plasma spray coating method.
