FUEL CELL TECHNOLOGY THE WAY TO GO FOR GHANAS ENERGY SUFFICIENCY.
The demand for energy in the country is very high but the country still depends on hydroelectric and thermal plants for the supply of energy. This problem has led to inefficient operation of industries such valco, Aluworks, wahome steels ect. Also the building of new high power industries has become a problem due to insufficient energy supply, it is therefore expedient that the nation looks at other ways of providing energy to meet the current energy demand in the nation. In view of this I will like to propose the use of the fuel cell technology in homes and low power industries while the hydroelectric and thermal plant will be used to feed the high power industries in the nation.
The Fuel Cell
The fuel cell technology employs a fuel cell to generate electricity by a chemical reaction. Every fuel cell has two electrodes, the anode and cathode. Which are positively and negatively charged respectively. The reactions that produce electricity take place at the electrodes. 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 combine to form water. A single fuel cell generates a tiny amount of direct current (DC) electricity and in practice; many fuel cells are usually assembled into a stack. Cell or stack, the principles are the same. The electrical current that is produce can be directed outside the cell to do work, such as powering an electric motor or illuminating a light bulb or a city. Because of the way electricity behaves, this current returns to the fuel cell, completing an electrical circuit. The...
