Hydrogen: Future Fuel? examines the chemistry behind the production of hydrogen by electrolysis, the use of hydrogen via a fuel cell to produce electricity and its application in the development of future transport vehicles. Students will construct and operate model electrolysis cells and model fuel cell vehicles.
In session one, students examine the properties of hydrogen and the production of hydrogen by electrolysis. They gain a basic understanding of the chemistry of electrolysis including terminology such as anode, cathode and electrolyte. Students use model electrolyser cells to produce hydrogen that can then be directed to a fuel cell.
In session two, students further explore the chemistry of fuel cells and their applications including building a fuel cell powered vehicle. Students will discuss some of the technological aspects of the processes particularly the use of sustainable energy to facilitate the electrolytic process and the design of future vehicles.
Students will cover some of pros and cons for this form of power for vehicles in the future.
Key Learning Outcomes:
- Explain how Hydrogen gas can be produced by electrolysis
- Describe how a fuel cell operates
- Construct a model vehicle powered by a hydrogen fuel cell
- Discuss pros and cons for the use of fuel cells in powering vehicles in the future
Learning Standards (Australian Curriculum):
Hydrogen – Future Fuel demonstrates the learning addressed through Year 10 of the Australian curriculum standards. In particular, it addresses:
- Different types of chemical reactions are used to produce a range of products and can occur at different rates (ACSSU187)
- Energy conservation in a system can be explained by describing energy transfers and transformations(ACSSU190)
Science as a human endeavour
- Advances in scientific understanding often rely on developments in technology and technological advances are often linked to scientific discoveries(ACSHE192)
- People can use scientific knowledge to evaluatewhether they should accept claims, explanations or predictions (ACSHE194)
- Advances in science and emerging sciences andtechnologies can significantly affect people’s lives, including generating new career opportunities(ACSHE195)
- The values and needs of contemporary society can influence the focus of scientific research(ACSHE230)
Science inquiry skills
- Critically analyse the validity of information in secondary sources and evaluate the approaches used to solve problems (ACSIS206)
- Communicate scientific ideas and information for a particular purpose, including constructing evidence-based arguments and using appropriate scientific language, conventions and representations (ACSIS208)
