Abstract
This paper proposes a novel cooling system for hydrogen fuel cell cooling systems by integrating heatpump technology to enhance operational efficiency. The study analyzed the cooling efficiency of the fuel cellcooling system. With the increasing focus on eco-friendly vehicle technologies to address environmental concernsand global warming, the transportation sector, a major contributor to greenhouse gas emissions, needs technologicalenhancements for better efficiency. The proposed cooling system was modeled through 1-D simulations. Theanalysis results of parameters such as thermal balance, temperature, and pressure of each component confirmed thestable operation of the system. By examining variations in the cooling system's flow rate, compressor RPM, andthe Coefficient of Performance (COP) based on different refrigerants, initial research was conducted to deriveoptimal operating conditions and parameter values.
