State-of-the-art air electrode supported SOFCs have exhibited significant improvements in performance, reliability, and ability to sustain thermal cycles, over previous tubular design. This has been confirmed by successful operation of two 25 kW power generation systems employing such cells. In addition, very significant cost reductions have been achieved by adopting non-EVD processes in cell production; further reductions in materials and processing costs will be realized when the programs currently underway are proven successful and are implemented in cell manufacturing.
