Gasoline and diesel fuels form the back bone of the have road transport. The internal combustion engine is being used in vehicles for the past 100 years approximately. But the problem with the engines is the limitation of fossil fuel reserves and the emissions of greenhouse gases responsible for global warming. These fossil fuels set about emissions of pollutants such as PM, Nox and CO which argon hazardous to the compassionate being.It is the need of the hour to vouch for other renewable energy sources to inhibit the energy crisis and to achieve decarburisation, energy security and promiscuouser air to breathe. evoke kiosks argon the devices that convert chemical energy to electrical energy without the emissions of poisonous exhaust gases.. This paper summarizes the configuration of the fuel kiosk hybridizing vehicle. It in brief describes the function of each component and the losses occuring in each component. furnish cellphones are the intimately quiet and reliable as they have no moving parts. The efficiency is about twice that of the internal combustion engine. 2. on that point is no Carnot limitation as in case of IC engine. The most commonly used fuel cell is hydrogen fuel cell in the polymer electrolyte membrane fuel cell (PEMFC). Hydrogen is a clean burning fuel. The exhaust is pure water.The combination of a fuel cell with a battery is studied in this paper. The hybridization of the fuel cell helps in reducing the size of the fuel cell and its initial cost but it increases the vehicle complexity, weight and the battery cost. At higher(prenominal) heaps and greater acceleration, the battery provides surplus power and increases the fuel cell efficiency. At low loads the fuel cell is used to provide the needed power. The battery is also used for the start up of the vehicle ... ...es by 2030. The cost of FCHEVs and BEVs are not largely touch on by the changes in electricity costs, but the ICE and FCEV costs are greatly affected by th e fuel cost. This occurs partially due to the different powertrain efficiencies.Comparing the boilers suit lifecycle costs, it can be observed that FCHEVs and BEVs are cheaper as compared to FCEVs and ICEs. But the FCHEVs and BEVs are sensitive to the overall capital and running costs. For instance, the BEVs in particular are sensitive to battery size. The lifecycle costs of ICEs and BEVs are about 1.75 times higher than that of the FCHEVs and the BEVs.There are several challenges that are to be met in the beside future for the FCHEVs to achieve commercialization, reliability, cost effectiveness and performance. Fuel cell hybrid vehicles can definitely be the clean technology used in the future of automotive engines.
