Development of Hydrogen Fuel Cell Bus Technology for Urban Transport in India

Tata Motors Ltd.-Yogesha S A, Smitan Brahmbhatt, Munusamy Raja, Suresh Arikapudi, Bhaveshkumar Bhut, Jaikumar V
Published 2019-01-09 by SAE International in United States
Polymer Electrolyte Membrane Fuel Cell (PEMFC) technology is considered for automotive applications due to rapid start up, energy efficiency, high power density and less maintenance. In line with National Hydrogen Energy Roadmap of Govt. of India that aims to develop and demonstrate hydrogen powered IC engine and fuel cell based vehicle. TATA Motors Ltd. has designed, developed and successfully demonstrated “Low Floor Hydrogen Fuel Cell Bus” which comprises of integrated fuel cell power system, hydrogen storage and dispensing system.The fuel cell power system, converts the stored chemical energy in the hydrogen to DC electrical energy. The power generated is regulated and used for powering the traction motor. The development of fuel cell bus consists of five stages: Powertrain sizing as per vehicle performance targets, fuel cell stack selection and balance of plant design and development, bus integration, hydrogen refueling infrastructure creation and testing of fuel cell bus. Fuel cell stack integrated with balance of components, which includes air subsystem, hydrogen subsystem, and thermal management system and water recovery unit. Integrated fuel cell power system tested…

Severe air pollution in cities caused largely by vehicular emissions, which requires urgent remedial measures. As automobiles are indispensable modes of personal and public mobility, pre-emptive efforts are necessary to reduce the adverse effects arising from their operation. A significant improvement in air quality can be achieved through large-scale introduction of vehicles with extremely low emission such as hybrid-electric and zero emission vehicles. Range extension of electric vehicles (EVs) is also of utmost importance to alleviate the handicap of restricted mileage of purely plug-in EVs as compared to conventional vehicles.This paper presents development of a polymer electrolyte membrane (PEM) fuel cell stack used for the range extender electric vehicles. The Fuel cell stack for range extender vehicle operated in a dead end mode using hydrogen and air as open cathode. Stack is to design to meet various performance requirements such as frequent start-stop, ramp-up rate, drive cycle conditions, vehicle dynamics and a longer operation life. Air-cooled stack development employs cell flow channels design analysis(anode and cathode), membrane selection, gasket design and leak analysis, bipolar plate…
