Due to hydrogen's carbon-free nature, research and development on innovative and effective hydrogen production techniques has received a lot of attention recently. This paper proposes and examines the use of nanoparticles to improve a combined solar-based hydrogen generation facility. The combined system employs a parabolic trough collector in conjunction with an organic Rankine cycle to generate electricity, which is then used in a polymer electrolyte membrane electrolyzer to produce hydrogen. The system performance of the nanofluids Syltherm-800/Cu and Syltherm-800/CeO2 as heat transfer media in the solar collector is assessed and contrasted with that of the base fluid, Syltherm-800. Thermodynamic models for the system components are developed and verified. According to the obtained results, the highest useful energy and exergy gains by the parabolic trough collector are found to be 6040 W and 1592 W, respectively, resulting in energy and exergy efficiencies of 67.74 % and 20.5 %. It is observed that Cu- and CeO2-based nanofluids have nearly identical effects on the system's overall performance, leading to higher hydrogen production compared to the base fluid. The total annual hydrogen production amounts are determined to be 20.580 kg, 21.575 kg, and 21.555 kg for Syltherm-800, Syltherm-800/Cu, and Syltherm-800/CeO2, respectively.
