Fuel cell and supercapacitors remote control car

Abstract

The energetic crisis and the actual fossil fuel dependant society make an alternative energy sources necessary. In a world where pollution is massively emitted and consumption has no end a cleaner energy source is needed. The hydrogen is a very good option because its use is very clean and is the more common element in the universe and also abundant in the earth. Nevertheless the hydrogen also has some disadvantages like high flammability, expensive obtaining and difficult storage. To solve or decrease these disadvantages the hydrogen must work with other energy sources like supercapacitors. If newer technologies are developed, more investigation will be done and the hydrogen problems will be solved with time. In this report of a 5 month project all the technological aspects involved in the conception and creation of a hydrogen car are explained.

The purpose of this project is to make an approach of a real and nowadays car industry problem: Energy management of an electric hybrid car. The car in this project is five times smaller and its power needs are lower too, but the problem in managing the different power supplying sources remains. In this actual project the power supply sources are a 300 W fuel cell and a 29 F supercapacitor. To make an accurate approach to the real problem the real requirements are tried to be accomplished: - Same acceleration as Porsche 911GT: The speed reached by a remote control car won’t be the same as the real car, but the acceleration of the car can be the same but in a lower speed. The Porsche 911GT reaches 100 km/h in 4,2 seconds (a = 6,614 m/s2), so this car would do the same if it could reach 100 km/h. - Brake: The brake system is an essential system for any car and must guarantee a rapid stop of the car. - Reverse gear: This is important to park a car and do some maneuvers occasionally. Some of these requirements are essentials and others are not and there are also very difficult requirements and easier requirements. All of them are kept in mind while doing this research project.
