Abstract:	In this work, the polyethylene glycol (PEG) hybrid material composited with tungstovanadogermanic heteropoly acid was prepared. Infrared (IR) spectrum revealed that the Keggin structure characteristic of the ${text{GeW}}_{{11}} {text{VO}}^{{5 - }}_{{40}}$ anion was present in PEG hybrid material. At room temperature (20°C), the conductivity of the sample is 4.07×10⁻³ S cm⁻¹. The results indicated that it is a new kind of excellent high-proton conductor. According to the experimental results, we proposed a possible mechanism of the proton conduction of the hybrid materials.
