CAIE IGCSE Chemistry Hydrogen Fuel Cells Compared with Petrol
Cambridge IGCSE Chemistry 0620 syllabus for exams in 2026, 2027 and 20282026–2028

Practise comparing hydrogen fuel cells with petrol engines using emissions and efficiency benefits alongside storage, leakage, supply and cost limitations.

How this is tested

  • credit water-only operation and no carbon dioxide at the vehicle, while avoiding zero-impact claims
  • compare useful energy per mass or efficiency when numerical fuel data are provided
  • weigh difficult high-pressure storage, leakage, availability, infrastructure and catalyst cost

A

Hydrogen is a non-renewable resource.

B

Hydrogen is produced during the fractional distillation of petroleum.

C

Hydrogen-oxygen fuel cells do not release carbon dioxide.

D
