A Vital Source of Energy for 21st Century: Review On Alkaline Fuel Cell

Abstract

A cell which converts the chemical energy into electric energy as eco-friendly way on the principle of electrochemical and Inverted by Sir William Grove in 1839 is known to be "fuel cell". It became a vital source of energy for the 21st Century. Different types of fuel cell are invented based on their working temperature and a type of material has been used in which alkaline fuel cell is one of the best. Fuel cell is an electro-chemical energy converter at the simplest conceptual level it's combined hydrogen with oxygen to produced water and electricity. It does not store the energy itself. It is flow process which draws liquid or gaseous fuel from separated tank and if necessary converse it to hydrogen in reformer. The hydrogen is taken combined with oxygen air in the fuel cell to produced water and electricity. The energy conversion process in the fuel cell is therefore intrinsically clean and silent. Generally other fuel such as natural gas, methanol, ethanol and even coal can also be used. The object of this study is to summarize the characteristic of the alkaline fuel cell.
