The stability of tubular metal supported SOFC has been studied as a function of current load, thermal cycles and interconnect-sealing concepts. Long term testing under applied current at 800ºC have been performed over 1000 hours on standard cells. Thermal cycles have been proven intensely (250 cycles) during over 700 hours. Major cause for degradation has been identified in terms of the anode interconnect-sealing design, which involves specific handling and machining of tubes and generation of initial submicron cracks. Cell microstructure seems stable after 1000 hours testing at 300 mA/cm2 and 800ºC. |
