This work aims to study on the performance of the SDC-based SOFC with a direct internal reforming of methane at lower temperature in the range of 600–750 ºC. The model of SDC-based SOFC with direct internal reforming mode is simulated and validated. The predicted results are in a good agreement with experimental data. The simulated results indicate that the molar flow rate of the hydrogen produced from the methane steam reforming reaction is higher as an increasing temperature. Moreover, the cathode activation overpotential is obviously reduced. Thus, the increase of temperature from 600 to 700 °C can enhance the average power density of SOFC from 0.19 to 0.42 A/m<sup>2</sup>.

The use of biogas and ethanol as fuels for solid oxide fuel cell-gas turbine (SOFC-GT) hybrid system needs an external steam reformer. As the operation of steam reformer and air preheater requires high external energy input, the efficient heat management of the SOFC system is necessary. Thus, the aim of this study is to analyze the recycling of the SOFC exhaust gas in a SOFC-GT hybrid system utilizing fuels such as ethanol and biogas. The effect of the recirculation ratio of the anode exhaust gas on the performance, the SOFC efficiency, the turbine to SOFC power ratio, and the overall efficiency of hybrid system was first investigated. Additionally, the recirculation of both anode and cathode exhaust gases in the SOFC-GT hybrid system was studied.

An ethanol reforming and solid oxide fuel cell-gas turbine (SOFC-GT) hybrid system with anode and/or cathode recirculation is investigated in this study. The aim is to analyze the effect of the anode and cathode recirculation on the performance of SOFC-GT system. The results showed that the hybrid system with both the cathode and anode recirculation achieve the highest system efficiency.
