Nowadays, the use of modern energy has become widespread due to problems such as air pollution, scarcity of fossil fuels and oil resources, and heating of the soil. To this end, the use of clean and non-pollutant energy in the automotive industry is necessary. Fuel cell cars also look attractive to replace the internal combustion engines due to their high efficiency, low emissions, and low noise and high power density, but they require proper thermal management for proper and safe operation and appropriate thermal management. It boosts scrolling and boosts the performance of these cars. High-temperature polymer fuel cells have recently been taken into account because of the advantages they have in comparison with low-temperature polymer fuel cells. some of these advantages are that it can be improved kinetics of the reaction, elimination of wetting systems for incoming gases, reduction of water management complexes and cooling systems, the possibility of using hydrogen with a low purity percentage and... In this study, the effect of electrical conductivity of the gas diffusion layer, the electrical conductivity of the membrane, as well as the effect of working temperature on a high-temperature polymer fuel cell has been investigated. Then, the effect of these factors on the dimensions of a car on the performance and scanning of a fuel cell vehicle was investigated and Studied. The results show that increasing the conductivity of the membrane and GDL layer improves the performance of the fuel cell. The results also show that at temperatures between 160 and 180 ° C, high-temperature fuel cells with a polybenzimidazole membrane and 14.5% phosphoric acid have the best performance. Also, the use of high-temperature polymer fuel cell in the FCV vehicle increases the car's mileage by about 10% compared with low-temperature fuel cell.
