  • AbstractThe phosphonated methylcellulose polymer as a proton conductor was prepared by stirring a solution of methylcellulose and distilled water with H3PO4 as dopant salt for ∼24 h. The molarity of H3PO4 was varied from 1 to 4M. The phosphonated samples were prepared in the form of membrane by solution cast technique. The stabilities of these membranes were checked by monitoring the conductivity as a function of time when stored at high relative humidity (RH = ∼80%). Conductivity was measured… CONTINUE READING
