Abstract

The limited resources of fossil fuels, the technical problems of existing vehicle and their emissions, have made the study of efficient energy converters and clean fuels a priority for research centers and automobile companies in the world. Using a hybrid or non-hybrid FC system in common cars can solve some of the problems of these vehicles. Therefore, in this article, a Polymer Electrolyte Membrane FC (PEMFC) system for use in a vehicle is investigated. Modeling is done by MATLAB software. According to the specifications of real samples, system components including stack, hydrogen and air humidifier, air compressor, humidifier pump, and cooling pump are modeled. The results show that 14% of the power of the FC stack is consumed by the peripheral components. The results show that 14% of the power of the FC stack is consumed by the peripheral components. In the basic state and at j=0.7 A/cm^2, the total efficiency of the system is 48.15% and the net efficiency of the system is 34.3%. By fully condensing the water vapor coming out of the stack and using it to humidify the reactors, there will be no need for an additional water tank to humidify the reactors. For j<0.047 A/cm^2, the stack cannot supply the required power of the system components, so the system needs an auxiliary energy source such as a battery to start working.
