  SEMINAR SYNOPSIS ON FUTURE SOURCE OF ENERGY “FUEL CELL”  GURU TEGH BAHADUR INSTITUTE OF TECHNOLOGY (Guru Gobind Singh Indraprastha University) SUBMITTED BY: MANMEET SINGH 02513204911  FUTURE SOURCE OF ENERGY FUEL CELL ABSTRACT Presently world’s energy needs is largely met by fossil fuels. Rapid industrialization and economic growth witnessed in the past century demanded large amount of energy and this resulted in faster depletion of fossil reserves. In future, not far from now, the fossil fuels will become scarce and costly. Other disadvantage is the environmental degradation. Still energy needs are growing in developing countries at a steady rate. Hence, mankind is continuously searching for a lasting solution for energy needs which will also be environmentally friendly. Fuel cells could be a major and necessary source of energy within a decade. They have great potential as the basic elements of large and small stationary  power plants and as the source of electricity for vehicles and smaller devices. Their size and shape are flexible and adaptable. They are modular, have no moving parts, operate without combustion, are comparatively efficient and reliable, and are nearly silent, generally do not pollute the environment, and are quite safe. The future of power and transportation will change dramatically when fuel cells become the main  producers of clean energy. The car will no longer be an environmental burden, and the electrical grid will  be subdivided to the neighborhood and building level. The quality and reliability of this alternative energy source will be superior to the current grid design. Fuel cells and hydrogen technology will make all of this  possible, and with little or no pollution. INTRODUCTION Fuel cells are important future sources of electrical power and could contribute to a reduction in the dependence on fossil fuels. They are electrochemical devices similar to a battery and consist of a container, an anode, a cathode, catalysts, an intervening electrolyte, and an attached electrical circuit. In most fuel cell systems, hydrogen is supplied to the anode and oxygen to the cathode which results in the  production of electricity, water, and heat. Fuel cells are comparatively efficient and reliable, have no moving parts, operate without combustion, and are modular and scale-able.   Every fuel cell also has an electrolyte, which carries electrically charged particles from one electrode to the other, and a catalyst, which speeds the reactions at the electrodes.   Hydrogen is the basic fuel, but fuel cells also require oxygen. One great appeal of fuel cells is that they generate electricity with very little pollution  –  much of the hydrogen and oxygen used in generating electricity ultimately combines to form a harmless byproduct, namely water.     REFERENCES 1. 2.   International Fuel Cells, A United Technologies Company, 2000a, How does a fuel cell work?:  3.   Electro-Chem-Technic, 2001, Fuel Cells: http://  4.   Society of Automotive Engineers, 2001, Fuel cell technology showcase:
