Proton conducting polymer electrolytes of methylcellulose doped ammonium fluoride: Conductivity and ionic transport studies

Methylcellulose (MC) was used as polymer host and Ammonium Fluoride (AF) salt was used as the proton donor. A proton-conducting solid polymer electrolytes (SPE) was prepared by the solution casting method. The highest ionic conductivity at room temperature is 6.4 x 10(-7) Scm(-1). The ionic mobility and diffusion coefficient that was calculated in this work is in good agreement with the increment of weight percent (wt %) of acid concentration. The value of cation of diffusion coefficient and ionic mobility was higher than value of anion. Thus, the results proven that the present samples were proton conductor.
