Electrode potentials and fuel cells
Understand standard electrode potentials, electrochemical cells, fuel cells and their applications
What you'll learn
- 1
Imagine two beakers of coloured liquid connected by a salt bridge – that's an electrochemical cell! ⚡
- 2
What flows through the wire connecting the two beakers?
- 3
Drag the salt bridge to connect the two half-cells and complete the circuit.
- 4
Let's calculate the standard cell potential for a zinc–copper cell.
- 5
Now build a hydrogen fuel cell – combine hydrogen and oxygen to make electricity and water.
- 6
In a hydrogen fuel cell, what is the only waste product?
- 7
What is the standard cell potential if E°(cathode) = +0.80 V and E°(anode) = –0.44 V?
