摘　　要：Undecatungstocobaltoruthenic polyoxometallic acid H7[Ru（H2O）CoW11O39] 22H2O was synthesized by the stepwise acidification and the stepwise addition of solutions of the component elements as well as the ion ex changing-cooling method. The optimal proportion of the component compound and the pH of the synthesis reaction were given. The product was characterized by means of inductively coupled plasma（ICP）, IR, UV and thermal analy sis. The IR and UV results indicate that H7[Ru（H2O）CoW11O39] 22H2O possesses the Keggin structure. The results of AC impedance measurement show that its proton conductivity is 2.30×10-3 S/cm at room temperature（295 K） and a relative humidity of 75%.Undecatungstocobaltoruthenic polyoxometallic acid H7[Ru（H2O）CoW11O39] 22H2O was synthesized by the stepwise acidification and the stepwise addition of solutions of the component elements as well as the ion ex changing-cooling method.
