Using Chemical Reactions to Produce Electricity: Cells and Batteries

The video tutorial explains how cells and batteries produce electricity through chemical reactions. It covers the workings of a simple cell using zinc and copper in an electrolyte, highlighting the oxidation and reduction processes. The tutorial also discusses rechargeable cells, which reverse chemical reactions to restore potential difference, and batteries, which are multiple cells connected in series. Additionally, it explores hydrogen fuel cells, where hydrogen and oxygen react to produce water and electricity, emphasizing their potential as a sustainable energy source.

Describe how a rechargeable cell can be recharged.

What are the main components of a hydrogen fuel cell and their functions?
