Fuel cell membrane polymer electrolyte membranes have gained attention as suitable alternatives for internal combustion engines in vehicles due to various reasons such as the absence of harmful exhaust gases, quick startup, low operating temperature, and high efficiency. Thermal management plays a fundamental role in the optimal performance of polymer electrolyte membrane fuel cells. In this study, various cooling methods for a fuel cell membrane have been investigated using a three-dimensional two-phase model of the fuel cell in the ANSYS Fluent software. A heat pipe has been added to the cathode bipolar plate side to eva‎luate its impact on the cooling system. Considering the equivalent thermal conductivity of the heat pipe, heat transfer inside the heat pipe has been simulated using dimension and properties-based programming code, and this simulated model has been used to solve the problem. Different arrangements of heat pipes for cooling the fuel cell have been modeled in three-dimensional simulation software, and based on the results obtained in this study, it was observed that applying cooling using a heat pipe has a significant effect on parameters such as temperature uniformity, electrical power, and heat flux at the cathode outlet, reducing heat losses from 18 watts to 13 watts at the cathode outlet of a fuel cell. It also leads to a further increase in electrical power by up to 2.4 percent in a fuel cell, improving system performance.
