Activity description and learning aims:
  • The pupils are supposed to determine the efficiency of a hybrid hydrogen power plant with regard to various primary energy sources. The kit provides methods to change the energy sources, connection (series/parallel) and load.
  • knowledge: energy conversion; functional principles and properties of fuel cells; energy storage
    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 experiment; controversy about hydrogen
  • e.g. renewable energies kit from Horizon (see unit description)
Suggestions for use:
  • The pupils should think of possible ways to determine the efficiency of a hybrid hydrogen power plant, use them on different combinations of power plants and present their results easy to understand.
  • An industry visit at a hydrogen factory or expert interview is recommended.
Recommended questions:
  • How does a fuel cell work?
  • How does a hybrid hydrogen power plant work?
  • Which types of hybrid power plants are possible?
  • How efficient is your hybrid power plant?
  • Which parameters influence the efficiency of a hybrid hydrogen power plant?
