What is the everyday name for a chemical cell?
Fuel cell
Battery
Charger
Why does a chemical cell go 'flat'?
It runs out of electricity
The reactants are used up
The reactants leak out
What must a fuel cell be supplied with?
Oxygen only
Fuel only
Fuel and oxygen
How is a fuel cell different to a normal chemical cell?
It is continuously supplied with fuel and oxygen so that it does not run out
It does not contain chemicals
It requires a combustion reaction
What is the word equation for the reaction in a hydrogen fuel cell?
Hydrogen + oxygen → water
Hydrogen + oxygen → water + carbon dioxide
Hydrogen + oxygen → water + carbon monoxide
Which of these equations for the hydrogen fuel cell reaction is balanced?
H2 + O2 → H2O
2H2 + O2 → 2H2O
2H2 + O2 → H2O
What is the name of another reaction that has the same equation as the reaction in the fuel cell?
Combustion
Hydrogenation
Condensation
Which of the following is an example of a disadvantage to the user of a hydrogen fuel cell car?
The production of hydrogen produces air pollutants
There is no nationwide network of hydrogen fuel filling stations
There is a reduction is air pollution where the car is driven
Which of the following is an example of a benefit to the environment of a hydrogen fuel cell powered car?
It saves the driver money
There are very few hydrogen filling stations
A reduction in air pollutants where the car is driven
Why does the use of hydrogen fuel cell cars still produce some air pollutants?
Small quantities of air pollutants are released through the exhaust
Small quantities of air pollutants are released during refuelling
Some methods for producing hydrogen produce air pollutants
