Abstract

A fuel cell is most interesting new power source because it solves not only the environment problem but also natural resource exhaustion problem. In this paper a description of fuel cell operating principles is followed by a comparative analysis of the current fuel cell technology together with issues concerning various fuels. Appropriate applications for current and perceived potential advances of fuel cell technology are discussed. A brief account on evolution and working of different fuel cells namely SOFC, PEMFC, DFMC, PAFC, MCFC and AFC followed by their comparative analysis The potential application of fuel cells can be used in automotive vehicle in low cost that gives high performance and high efficiency. This investigation examines the economics of producing electricity from fuel cell systems under various conditions, including the possibility of using fuel cell vehicles (FCVs) to produce power when they are parked at office buildings and residences. The analysis shows that the economics of both stationary fuel cell and FCV-based power vary significantly with variations in key input variables such as the price of natural gas, electricity prices, fuel cell and reformer system costs, and fuel cell system durability levels. The Grid-connected FCVs in commercial settings can also potentially supply electricity at competitive rates in some cases producing significant annual benefits particularly attractive is the combination of net metering along with time of- use electricity rates that allow power to be supplied to the utility grid at the avoided cost of central power plant generation. FCV based power at individual residences does not appear to be as attractive, at least where FCV power can only be used directly or banked with the utility for net metering and not sold in greater quantity, due to the low load levels at these locations that provide a poor match to automotive fuel cell operation, higher natural gas prices than are available at commercial settings, and other factors. In the long term, a hydrogen-based economy will have an impact on all these sectors. In view of technological developments, vehicle and component manufacturers, transport providers, the energy industry, and even householders are seriously looking at alternative energy sources and fuels and more efficient and cleaner technologies - especially hydrogen and hydrogen-powered fuel cells. At the end of the paper some potential application of fuel cell that are capable of catalyzing revolutionary impact on energy scenario are being discussed, along with the advantages and disadvantages/ limitations of fuel cells.
