Synthesis and characterisation of PVdF-{(NH4)2[C4H8 (COO)2]}: CNT gel electrolyte for Lt fuel cell application

In the present work, improvement of ion transport property in poly (vinylidene) fluoride (PVdF) - based polymer electrolytes for the use of low temperature fuel cell application have been investigated using CNT as fillers. The effect of filler, on structural and electrical behavior of electrolyte were studied by different experimental tools namely, XRD, Optical microscopy, impedance spectroscopy, and dielectric relaxation measurement. Improvement in amorphous nature and ionic conductivity has been observed for PVdF based polymer electrolytes dispersed with CNT filler particle. Dielectric plots show dispersive nature of relaxation time and hopping mechanism appears to be responsible for ionic conduction of the nanocomposite polymer electrolyte.
