Electrochemical Cells

Electrochemical Cells and Fuel Cells Bundle

This bundle contains the lessons, powerpoints and all relevant resources for teaching the Separate Science GCSE Chemistry AQA content on electrochemical cells and fuel cells. This bundle contains 3-4 lessons of content including: **Lesson 1: What are Electrochemical Cells?** Lesson Objectives: * Describe what an electrochemical cell is and what we use it for * Describe how to make an electrochemical cell * Identify factors which affect the size of the voltage produced by an electrochemical cell This lesson contains: * Lesson powerpoint * Student practical investigation * Teacher notes on how to deliver lesson slides/content and answers **Lesson 2: How do Electrochemical Cells Work?** Lesson Objectives: * Recall the definitions for oxidation and reduction * Identify which elements are oxidised and reduced in an electrochemical cell * (H) – write half equations for oxidation and reduction taking place in electrochemical cells * Explain why alkaline/non-rechargeable batteries eventually stop working This lesson contains: * Lesson powerpoint, containing animation about how electrochemical cells produce electrical current and the reactions that take place within it * Student exam questions (23 marks worth) from AQA syllabus with mark scheme * Teacher notes on how to deliver lesson slides/content and answers **Lesson 3/4: What are Fuel Cells?** Lesson Objectives: * Describe, in basic terms, how a hydrogen fuel works * (Higher only) write balanced half equations for the reactions taking place inside a hydrogen fuel cell * Describe advantages and disadvantages of hydrogen fuel cells * Evaluate the use of hydrogen fuel vehicles compared to electric and petrol vehicles Lesson resources include: * Lesson powerpoint with printable diagrams for students * Explanations of half equations from fuel cell (both acid cell (not AQA) and alkaline cell (AQA) version) and balancing them * Relevant video links * 6 marker question and mark scheme * Exam question pack on fuel cells and energy * Plenary AFL multiple choice quiz and debate activity
