On the occasion of the Council of Scientific and Industrial Research (CSIR) Foundation Day, the President of India recently introduced India’s first indigenously developed high-temperature based Fuel Cell System.
- It is developed under the Public-Private Partnership (PPP) model by the Council of Scientific and Industrial Research (CSIR) in partnership with Indian industries.
- It is built under India’s flagship programme named ‘New Millennium Indian Technology Leadership Initiative (NMITLI)’.
- The developed fuel cells are based on High-Temperature Proton Exchange Membrane (HTPEM) technology.
- It is a 5.0 kW fuel cell system that generates power in a green manner.
- It takes methanol or bio-methane as the input and produces heat and water as its bi-products, which can be further used.
- This helps to attain an efficiency that is greater than 70%, which is difficult to achieve by other energy sources.
High-Temperature Proton Exchange Membrane (HTPEM) Technology
- High-Temperature Proton-Exchange-Membrane (HTPEM) is the core of the fuel cells that run above 150 °C. It works on two modes of operation with respect to the source of fuel.
- One mode is based on the conversion of natural gas into Hydrogen by means of steam reforming. This mode is used to fulfill stationary power demands.
- Steam reforming or steam methane reforming is a chemical synthesis process for producing syngas (hydrogen and carbon monoxide) from hydrocarbons such as natural gas.
- The second mode is based on the operation of Hydrogen with Oxygen obtained by the process of electrolysis. This is generally used in the space-related applications.
- Electrolysis is a chemical decomposition process in which an electric current is passed through a liquid or a solution containing ions.
- This fuel system is most suitable to fulfil distributed stationary power applications demands like in small offices, commercial units, data centres, etc. where highly reliable power is essential with simultaneous requirement for air-conditioning.
- This system will meet the requirement of efficient, clean and reliable backup power generators that are demanded by telecom towers, remote locations, and strategic applications.
- The Fuel Cells fit well in India’s mission of replacing Diesel based Generating (DG) sets with the green and alternate fuels.
- This development is therefore expected to reduce India’s dependence on crude oil.
