Experimental investigation of novel proton exchange membrane fuel cell and battery integrated system
(2023-08-01) Acikalin, Guven; Dıncer, Ibrahim
In this thesis study, a PEM fuel cell and battery integrated system is developed. The performance assessments of the PEM fuel cell stack are performed through the polarization curve, energy efficiency, exergy efficiency, and open circuit voltage. Furthermore, the performance evaluation of the fuel cell and battery integrated system is performed. The performance assessments of the system are performed through the energy and exergy efficiencies. Moreover, the effect of varying humidifier temperatures on the PEM fuel cell stack is studied. The energy and exergy efficiencies of the PEM fuel cell stack are increased with increasing the humidifier temperature. The highest energy and exergy efficiencies of the developed integrated system are calculated as 6.18% and 6.28%, respectively, while the highest energy and exergy efficiencies of the PEM fuel cell stack are obtained as 14.7% and 14.9%, respectively.
