The aim of this work is to analyze system efficiency when anode-off gases are recirculated at a diesel driven solid oxide fuel cell system. Diesel was chosen as a fuel due to advantages of its high energy density and well-established infrastructure. Three systems were mainly investigated which have different system configurations. First system does not use recirculation of anode-off gas at the system. At second model anode-off gases are recirculated to a diesel reformer in the system. Finally anode-off gases are recirculated to the anode side of a solid oxide fuel cell stack. Three different systems are compared in terms of total efficiency, performances of diesel reformer and solid oxide fuel cell. It was found that various inlet conditions and split conditions would make differences of total efficiencies and component performances at the three different systems.
