Activity description and learning aims:
  • The pupils are supposed to build a working model of a hydrogen vehicle. They may take cues from existing vehicles and copy their form and features, discuss their own design ideas and make a list of needed material. Try and error methods can be used to achieve maximum efficiency.
  • knowledge: energy conversion; functional principles of fuel cell and electric motor; properties of fuel cells and electric motors
    inquiry: observation; description; creating and proving a hypothesis; systematizing; planning, conducting and evaluating design task; using models; comparison
    communication: online research; literature research; lab notes; schemes; manuals; group discussion; tables; diagrams; formula
    appraisal: evaluation of design task; controversy about hydrogen
  • e.g. Hydrocar or H2 Racer from Horizon (see unit description)
  • electric motor(s), fuel cell, electrolytic cell, electric supply, cables, hydrogen storage
Suggestions for use:
  • The pupils should determine what factors influence the efficiency of a hydrogen vehicle, test them and present their results easy to understand.
  • An industry visit at a hydrogen vehicle factory or expert interview is recommended.
Recommended questions:
  • How does a fuel cell work?
  • Which materials do you need for building a hydrogen vehicle?
  • Which values influence the efficiency of your hydrogen car?
  • Whose hydrogen car is the best?
