In the 1960s, GM embarked on a pioneering project by equipping a van, the Handi-Bus, with a prototype fuel cell hydrogen power system. This project marked an early exploration of hydrogen fuel cell technology in the automotive industry. While NASA was using fuel cells for electricity generation in Apollo missions, GM was experimenting with the practical application of hydrogen on Earth. The fuel cell system created for the Handi-Bus, in collaboration with Union Carbide, was so massive that it transformed the van into a two-seater due to its size and weight. Despite its limitations in performance and practicality, this project was instrumental in showcasing the potential of fuel cell vehicles. The Handi-Bus project was a test-bed initiative, demonstrating that fuel cell technology could work and laying the foundation for more efficient and compact successors. Nearly six decades later, GM's commitment to hydrogen fuel cell technology continues, with advancements like the Hydrotec fuel cell cubes. GM sees these fuel cell systems as more suitable for large commercial vehicles like mining trucks, while batteries remain preferred for lighter passenger cars and SUVs. This historical project highlights GM's enduring exploration of alternative powertrains and their belief in the efficiency and versatility of fuel cell technology in the automotive industry.
