In present paper is reported the first successful observation of the electrochromic effect of polyvanadium- molybdenum acid H2V10Mo2O31+/- y(DOT)nH2O xerogels. Thin films of the investigated compound were produced by sol-gel technology. The transmission spectra were measured in the visible and infrared wavelength range. IN the all wavelength regions the transmission spectra changes when the dc electrical field was applied to the film. IN the visible wavelength range were observed the reversible changes of the film color. IR spectroscopy measurements of the films were carried out to obtain information about the water content in the film when the current flows through the sample. The electrochromic effect in the investigated compound is related with the proton motion through the xerogel that is acting by dc electrical field.
