Abstract:
This paper shows an exhaustive presentation and complementary discussions on various aspects of works done recently on the developments of composite membranes for polymer electrolyte fuel cell (PEFC) applications. The electropolymerisation of Polyaniline/Ag (PANI/Ag) and poly(o_methylaniline)/Ag (PoMeANI)/Ag nanocomposites were prepared by insitu oxidative polymerization of aniline monomer in the presence of different concentrations of Ag nanoparticles. The formation of PANI/Ag and its derivative nanocomposites was characterized by FTIR and UV–vis spectroscopy. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were used to investigate the electrochemical properties Polyaniline/Ag and poly(o_metylaniline)/Ag .CV and EIS results show that the PANI/Ag film exhibits considerably higher electroactivity compared with its derivative. The research interest is to implement the conducting polymers in fuel cell technology, as Membrane Electrolyte fuel cell components or conducting supports for noble metal deposition.
