Fuel Cells

hydrogen oxygen fuel cell advantages

• quiet

• does not produce CO₂

• not toxic to dispose of

• efficient release of energy

• can be fuelled from a renewable source

• water is the only product

• produces a constant voltage as long as refuelled

• raw material can be made using electrolysis

chemical cell advantages

• quiet

• does not produce CO₂

• can easily be recharged

• efficient release of energy

• can be fuelled from a renewable source

petrol/diesel advantages

• not toxic to dispose of

• easy to refuel

• widely available

hydrogen oxygen fuel cell disadvantages

• difficult to refuel

• not widely available

• difficult to store

• fuel is a gas so might leak

chemical cell disadvantages

• creates toxic waste when disposed of

• voltage gradually decreases over time

• raw material need to be mined from underground

• mining causes environmental damage

petrol/diesel disadvantages

• noisy

• produces CO₂

• insufficient release of energy

• not fuelled from a renewable source

• raw materials need to be mined from underground
