ALTERNATIVE FUEL FOR FUEL CELL POWERED VEHICLES

In response to the ever - growing concerns for envir onmental protection, the development of cleaner, more energy efficient, environmentally friendly vehicle while maintaining vehicles performance, comfort & safety. For more than 60 years automobile industries has working for an various alternative power sou rce vehicles & has place varieties of vehicles on the road, Though the most challenging task for automobile scientists is to provide a pollution free vehicle. But the situations become a worldwide phenomenon so there is need to go alternative fuels for aut omobiles. To overcome above problem fuel cell vehicle (FCV) is the best. It achieves twice the efficiency & near a zero emission with the only by product being pure water. The PEM fuel cell proposed for future vehicles, hydrogen as a fuel supplying hydrog en gas or hydrogen ? rich reformer is critical issue. A large no. of fuel source can be used to provide the hydrogen, each has benefits & limitations. This paper will explore the alternative fuel cell issue, fuel cell; it’s working, & highlighting the advan tages, disadvantages of hydrogen, methanol reformer, hydrocarbon (gasoline) reformer and FCVs.
