چکیده:

A fuel cell is a compatible technology with environment, for production of energy with high yield efficiency and the least amount of environment pollution. A fuel cell is an electrochemical conversion device, as a result of fuel cell function, chemical energy of fuel changes into electrical energy. One of the most important elements of fuel cells is source of materials used to produce electricity. The main employed sources in fuel cells are hydrogen and oxygen. Hydrogen is such as available from different sources, methanol, ethanol, natural gas, propane, petroleum, coal, gazoline, petrol and microbial and biological sources. Oxidants for fuel cell are air and oxygen with platinum catalyst. In microbial fuel cells, motor power is an oxidation reactions and reduction of a primary substance from kind of carbohydrate such as glucose. In This paper we discuss about several sources used in fuel cells as well as their advantages and disadvantages.
