The challenge of designing, building, and testing a hydrogen-powered city car represents not only a quest for efficiency and mobility but also a commitment to sustainability and innovation. This enterprise requires a systematic approach, combining advanced engineering, cutting-edge technology, and a clear vision of a greener future. The process begins with the conceptualization of the vehicle, where 6 teams of students from IST collaborate to create a car that meets the needs of urban areas. The focus is on space efficiency, maneuverability, and aerodynamic design. Additionally, it is necessary to integrate hydrogen fuel cell systems, ensuring that the vehicle is powered cleanly and sustainably. This leads to the construction phase, where precision and technical excellence are paramount. Every component of the car is carefully manufactured and assembled, from the chassis to the fuel cell. The flawless operation of the car’s different elements is essential to ensure optimized performance and reliable operation. After the construction is completed, the car undergoes rigorous testing to ensure its safety, efficiency, and performance. Driving tests in simulated urban conditions help refine the vehicle’s control, while endurance and durability tests ensure its reliability and safety. Additionally, emissions tests ensure that the car meets the highest sustainability standards. At the end of this process emerges a hydrogen-powered urban car that not only offers a clean and sustainable alternative to conventional vehicles but also paves the way for a new era of urban mobility, with zero pollutant emissions and a reduced environmental footprint. This is a crucial step towards a more efficient and greener future for cities around the world. From this moment forth, drawing upon the knowledge accrued through the development of our inaugural vehicle, the TFC01, we are embarking upon the planning and initiation of the construction of our new vehicle, the TFC02, which will integrate enhancements and evolve into an autonomous vehicle.
