Union Minister of State (Independent Charge) Science & Technology Jitendra Singh launched India's first indigenously developed Hydrogen Fuel Cell Bus developed by KPIT-CSIR in Pune.
The hydrogen fuel cell uses hydrogen and air to generate electricity, producing only heat and water in the process.
Hydrogen fuel cells like the one 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.
Just like conventional cells, a fuel cell consists of an anode (negative electrode) and cathode (positive electrode) sandwiched around an electrolyte.
