Green Hydrogen Fuel Cell Bus
Published on 21 Mar 2025
• The Minister of Petroleum & Natural Gas recently showcased India’s advancements in green hydrogen mobility by demonstrating a hydrogen-fuelled bus powered by IndianOil to the Prime Minister of Bhutan.
• A hydrogen fuel cell bus has three main Components: the fuel cell stack, the electric motor, and the hydrogen storage tanks.
• The fuel cell stack is made up of individual fuel cells that combine hydrogen and oxygen to produce electricity, heat, and water as byproducts.
• The electric motor is connected to the fuel cell stack and uses the electricity produced to power the bus.
• The hydrogen storage tanks store compressed hydrogen gas, which is supplied to the fuel cell stack.
• When the driver starts the bus, the hydrogen stored in the tanks is supplied to the fuel cell stack where a chemical process produces steam and energy.
