FUEL CELL TECHNOLOGY

ABSTRACT

The world’s energy consumption is increasing steadily at a rate of 1.6% per year. Consumers are developing new requirements, and developing economies want to achieve higher economic and social levels. In the span of the next ten years energy consumption will reach alarming levels. Currently 90% of this requirement is met using fossil fuels. Burning hydrocarbons liberates carbon oxide gases (CO & CO2) that have undesirable side effects. Another feature of hydrocarbons is that their reserves on Earth are limited. For all these reasons, the future energy supply will depend on the magnitude of the growth in demand, changing objectives and social priorities in response to these. The objective of this paper is to analyze the innovative processes in the field of fuel cell research which will provide a significant solution to the problems discussed above.

INTRODUCTION

A fuel cell burns a fuel in oxygen to make water and carbon dioxide (in the case of a carbon-containing fuel)

In a fuel cell, the reaction is done electrochemically, meaning that in the anode compartment the fuel is oxidized, and in the cathode compartment, oxygen from the air is reduced to water.

The two compartments are connected by an electrolyte that allows hydrogen ions (protons) to move from the anode to the cathode.
