CsH{sub 2}PO{sub 4} and H{sub 3}PW{sub 12}O{sub 40}6H{sub 2}O (WPA6H{sub 2}O) were mechanically milled by using planetary ball mill to obtain xCsH{sub 2}PO{sub 4}--(1-x)WPA6H{sub 2}O(%mol) composites. Characterizations of the composites indicate that there were changes of structure of CsH{sub 2}PO{sub 4}WPA composite after mechanical milling. {sup 1}H MAS NMR measurements suggested a hydrogen bond was newly developed between CsH{sub 2}PO{sub 4} and WPA which correlated with conductivity of the composites. 95CsH{sub 2}PO{sub 4}5WPA shows the highest conductivity at 70-170 deg. C range of temperature. The mechanical milling succeed to increase the conductivity under non-humidified atmosphere and intermediate temperature.
