Three types of products recycling are considered: cathode products recycling (CPR), anode products recycling (APR), and both cathode and anode products recycling (BACPR). In the present work,   operating temperature and  limiting current density was calculated from   governing equations by the trial and error method. Furthermore, the effect of pressure ratio and air utilization factor on the performance of the SOFC-GT hybrid system is considered. Results show that   CPR has more effect on the performance of hybrid systems than   APR. The total electrical efficiency of the hybrid system increases as the cathode recycle ratio (CRR) increases and decreases as the anode recycle ratio (ARR) decreases. In addition, results show that the hybrid system with BACPR can achieve a higher overall electrical efficiency of approximately 75%. https://hfe.irost.ir/article_486_c71d5390841a8c21c5ae3531ea79ee0c.pdf
