Every year, students in Science, Technology, Engineering and Mathematics (STEM) participate in Eco-Marathon competitions globally. The goal is to engineer the world’s most energy efficient vehicles.
For the Hydrogen fuel cell category, Spectronik has specially developed the Protium-375 Eco-Marathon Package – designed to eliminate the complexity of Hydrogen fuel cell system integration and help participants focus solely on breaking efficiency records.
We have utilized the same materials, product architecture and component reliability as the ones used in our military and aerospace programs to ensure that all vehicles powered by Spectronik fuel cells achieve their utmost potential.
Let’s work together towards highly efficient Hydrogen powered future mobility!
