摘要：

Thermal gasification and solid oxide fuel cell (SOFC) technologies represent an interesting combination for power generation, as high fuel flexibility and high electric efficiencies are expected. The TwoStage gasifier is a high-efficient downdraft gasifier fueled by wood chips that produces a very clean product gas with virtually no tar. This study operated an 800 We SOFC stack with product gas from the TwoStage gasifier for a total of 145 hours. Only minimal gas conditioning was used, including a bag filter, carbon filter, humidifier and desulphuriser. The obtained results show excellent part-load performance at 55% flow for the SOFC, with no loss in efficiency. High SOFC electric efficiencies up to 46.4% were measured at a fuel utilisation up to 90%, the highest reported values of such a system. The gasifier-SOFC system efficiency was estimated to 38-43%. No significant losses in SOFC performance were observed during the hours of operation.
