Jitendra Singh, Union Minister of State for Science and Technology, presented a hydrogen fuel cell bus built by KPIT-CSIR in Pune on Wednesday. The hydrogen fuel cell generates electricity from hydrogen and air, emitting only heat and water.

Hydrogen fuel cells, such as the one on the bus, generate energy by mixing hydrogen and oxygen atoms. The two gases react across an electrochemical cell comparable to a traditional battery cell to generate electricity, water, and tiny amounts of heat. Electric motors utilize this power to drive the car forward.

Like a normal cell, a fuel cell comprises an anode (negative electrode) and a cathode (positive electrode) sandwiched around an electrolyte. According to the US Department of Energy, fuel cells function similarly to traditional batteries seen in electric cars, except they do not run out of charge and do not require power to replenish. They continue to generate energy as long as hydrogen is available.

The anode receives hydrogen, whereas the cathode receives air. A catalyst at the anode splits hydrogen molecules into protons and electrons opposite the cathode. The electrons go via an external circuit, generating an electric current that may be utilized to electric power motors. Protons, on the other hand, pass through the electrolyte to the cathode. They combine with oxygen and electrons to make water and heat
