1. Fuel Cell – Why it could be better:
   From the table:

   Fuel cells don’t need to be recharged.

   They have a greater driving range.

   Refuelling is quicker than recharging a battery.

   From other knowledge:

   Hydrogen can be made using renewable energy (like from electrolysis).

   Fuel cells only produce water – so no pollution.

   Lithium-ion batteries can be dangerous – they can catch fire or release harmful chemicals when thrown away.

   Batteries wear out over time and stop working.

   ✅ Lithium-Ion Battery – Why it could be better:
   From the table:

   Batteries are more energy efficient.

   The cars and running costs are cheaper.

   Recharging is much cheaper than refuelling with hydrogen.

   From other knowledge:

   Hydrogen is usually made from fossil fuels (not renewable).

   It’s hard to find hydrogen filling stations, but charging points are everywhere.

   Hydrogen tanks take up space and are harder to store.

   Hydrogen can be explosive if not handled properly.

   Batteries also don’t produce pollution while running.
