Fuel cells

In this lesson, students will describe how cells and batteries can be made and how the voltage can vary. Students will describe how a fuel cell works and write half equations for the electrode reactions in a fuel cell. We will also evaluate the use of hydrogen fuel cells in comparison to rechargeable cells and batteries.
