Preserve our environment from the hazardous gases that vehicles release, which cause a rise in the greenhouse effect, Researchers have discovered a way to create a car with zero emissions and no contamination, making it environmentally friendly. In response to this concern, fuel-cell electric vehicles that run on hydrogen have been developed. In this work, ADVISOR was used to model the fuel cell systems seen in autos, and through comparisons, the models were examined. Vehicles’ fuel cell systems are crucial components. Therefore, before installing a fuel cell system in a car, it is essential to consider the system's coherence with the vehicle in terms of cost and security. It is simpler to compare such sorts of systems with the use of the ADVISOR tool. In this article, the implementation of the program was demonstrated using an example, several types of fuel cells were contrasted, and the outcomes were evaluated.
