Abstract
A novel concept for an atmospheric SOFC hybrid system applying a sub-atmospheric gas turbine is proposed. Based on a developed process model suitable operating conditions are studied. The resulting performance is compared to different state-of-the-art SOFC system concepts. The comparison shows that pressurized SOFC/GT systems offer the highest electric efficiency. The novel concept as well as a two-stage SOFC system offer lower efficiencies, but still well above 60 %. However, avoiding the complex system requirements of pressurized SOFC/GT systems, these concepts are promising for highly efficient electricity generation.
