The Council of Scientific and Industrial Research (CSIR) and KPIT have successfully run trials of India’s first Hydrogen Fuel Cell (HFC) prototype car running on an indigenously developed fuel cell stack at CSIR National Chemical Laboratory, Pune. The fuel cell is a low-temperature PEM (Proton Exchange Membrane) type Fuel Cell that operates at 65-75 degree Centigrade, which is suitable for vehicular applications.
CSIR and KPIT have successfully developed a 10 kWe automotive-grade LT-PEMFC fuel cell stack. The powertrain of the PEM fuel cell technology comes with a membrane electrode assembly, which was developed at CSIR. On the other hand, KPIT has shared its expertise in stack engineering which included lightweight metal bipolar plate and gasket design, development of the balance of plant (BoP), system integration, control software and electric powertrain that enabled running the fuel cell vehicle. The fuel cell stack uses extremely thin metal bipolar plates, thus reducing the stack weight by about two-thirds.
Hydrogen Fuel Cell (HFC) technology uses chemical reactions between hydrogen and oxygen (from the air) to generate electrical energy, eliminating the use of fossil fuels and pollution to the environment. The fuel cell technology emits only water, thus cutting down the emission of harmful greenhouse gases along with other air pollutants.
The trial round was conducted with a battery-electric passenger car platform, which was retrofitted with the fuel cell stack. However, it is expected that the technology is more suited for commercial vehicles (CV) such as buses and trucks. Battery electric buses/ trucks require a large battery to achieve the desired operating range, this increases the weight and reduces efficiency. In comparison, Hydrogen Fuel Cell technology requires a much smaller battery for a very large operating range. Hence, HFC technology offers more promise for the CV segment.
The fuel cell vehicle is fitted with a Type III commercial hydrogen tank. With a capacity of around 1.75kg of H2 stored at about 350 bar pressure, the eco-friendly car can run up to a range of 250km under typical Indian road conditions at moderate speeds of 60-65kph. The entire fuel cell stack and its associated components with powertrain were retro-fitted in a standard 5-seater sedan.
Commenting on this significant milestone, Ravi Pandit, chairman, KPIT said, “The technology has a great future and owing to its indigenous development, is expected to be more commercially viable than ever before. It is an important technology that will help India significantly reduce pollution and reduce our fossil fuel imports.”
Prof. Ashwini Kumar Nangia, director, CSIR-NCL, while congratulating the teams on their first successful car run on hydrogen fuel cell using indigenous CSIR-NMITLI technology and KPIT as an industry partner, stated that the time has come for renewable energy based on hydrogen as a fuel to power transportation in the country. This will not only reduce the petrol, diesel import bill but hydrogen is the cleanest fuel with water as the only by-product. Long-term investment of CSIR under NMITLI in a niche energy area has come to fruition.
