Abstract
This research paper mainly deals with a thermodynamic modeling and exergy analysis of a hybrid energy system consisting of a solar PV/T panel, PEM electrolysis, a polymer fuel cell (PEMFC), and single-effect Li-Br absorption chiller. Hydrogen is produced in this cycle using the electricity generated by PV/T panel, and it is stored in storage for later use at night when there the sun is not available. Hence, this cycle can be used at all hours of day and night. Solar radiation intensity per year is obtained by climate data of the capital city of Iran, Tehran. The effects of fuel cell current density on system efficiency, work and heat, voltage of system, and exergy losses in each component are investigated. Also, the exergy efficiency and the total cost rate for the objective function were used in an optimization problem based on the genetic algorithm. The results show that efficiency of energy and exergy of the cycle are 36% and 29%, respectively.
