Solid polymer electrolyte films of PMMA with NaClO 4 and NaClO 4 + plasticizer ( dimethyl foramide) have been prepared by solution cast technique. DC conductivity of the films was measured in the temperature range 303-393 K. The variation of ionic conductivity as a function of temperature in polymer electrolyte was analyzed. In the temperature range studied, three regions with different activation energies were observed. Transference number data showed that the charge transport in this system is predominantly due to ions only. Electrochemical cells of configuration Na/(PMMA+NaClO 4 +DMF )/(I 2 +C+electrolyte) were fabricated and the discharge characteristics of these cells were studied under a constant load of 100K:. Several cell parameters associated with the cells were evaluated and compared with earlier reports.
