Hydrogen as a pedalling aid
(PHYSorg.com Chemistry)

An e-bike fueled with hydrogen instead of electricity? No, this is not a utopia, but reality: industrial gas specialist Linde has developed a hydrogen pedelec equipped with a compact fuel cell instead of the usual battery. Florian Freund was inspired by the invention for his Matura thesis: He developed a prototype with which the hydrogen e-bike can be refuelled safely at the H2 filling station on the Empa mobility demonstrator move.
