Write short note on fuel cells vehicles.
✓

Answer

  1. Fuel cells vehicles (FCVs) are electric vehicles that use fuel cells instead of lead acid batteries to power the vehicles.
  2. Hydrogen is used as a fuel in fuel cells. The by product after its burning is water.
  3. This is important in terms of reducing emission of greenhouse gases produced by traditional gasoline fuelled vehicles.
  4. The hydrogen fuel cell vehicles are thus more environment friendly.
