Abstract
A new proton conducting polymer electrolyte PEO + NH4l system has been investigated. The solution-cast films of different stochiometric ratios have been prepared and characterized. Proton transport has been established using various experimental studies, namely optical microscopy, X-ray diffraction, differential thermal analysis, infrared, coulometry transient ionic current and electrical conductivity measurements at different temperatures and humidity. The maximum conductivity of the complexed material has been found to be ∼10−5 S cm−1. Both H+ ion and I− anion movements are involved with respective transference numbers and mobilities astH+=0.74, ,tl−=0.09, μH+=4.97 × 10−6 cm2 V−1 s−1 and μl−=7.65.
