A hydrogen fuel cell bus developed by KPIT-CSIR in Pune was unveiled by the Union minister of state for Science and Technology.
Key Points:
About Hydrogen Fuel Cell Bus
- Hydrogen fuel cells present in the bus produce electricity by combining hydrogen and oxygen atoms.
- The two gases react across an electrochemical cell similar to a conventional battery cell to produce electricity, water and small amounts of heat.
- This electricity is then used by electric motors to propel the vehicle forward.
Advantages of a Hydrogen Fuel Cell-Powered Vehicle:
Hydrogen fuel cell electric vehicles (FCEV) only emit water vapour and warm air. They do not produce any tailpipe emissions.
They are more efficient than internal combustion engine vehicles.
Hydrogen can be refilled in a fuel cell vehicle in a matter of minutes, nearly as fast as an internal combustion engine can be refilled with fossil fuels.
