ABSTRACT
Polymers are advanced materials which are widely used in every material in our daily life. The importance of Polymers have been high lightened by their applications in different dimensions of science, technology and industry. One of them among them are Fuel cells. Fuel cells are electrochemical devices which convert chemical energy into electrical energy. The fuel cell has attracted attention of everyone due to their potential. The Polymer electrolyte fuel cells are electrochemical cells that will easily convert chemical energy of a fuel directly into electrical energy. One among the polymer that is efficient and environmentally benign is chitosan. It is an important and abundantly available in renewable resources on the earth. This is a biopolymer that can be used in both membrane electrolyte and electrode. The application of chitosan as a novel biopolymer in the fuel cell technology can be obtained. The FTIR test is used to access the functional group present in the chitosan. The SEM is also used to analyze the chitosan. The main aim of this analyze is to evaluate the influence of molar mass and deacetylation degree of chitosan. The XRD (x ray diffraction) analyses was applied to characterization of crystallinity of native and cross-linked chitosan. The UV analysis is used to absorb the wavelength of chitosan. This review provides an overview of main available fuel cells following by application of chitosan as novel biopolymer in fuel cell technology.Key words: Polymers, Fuel cells, Electrochemical cells, Chitosan.
