- 18 - DESCRIPTIVE ABSTRACT The invention relates to an electronic conductive polymer doped by the anions of a hetero- polyacid of formula: Hn(XMyVy,Oz) in which n, y, y' and z are such that 2?n?6, 6?y?18, 0?y'?12, 24?z?70 and 6?y+y'?18, X being an element such as P or Si and M is Mo or W. These polymers can be prepared by chemical or electrochemical oxidation from a solution containing the heteropolyacid and the monomer able to form an electronic conductive polymer by oxidation, e.g. pyrrole, thiophene, aniline, paraphenylene diamine, acetylene, benzene and their substituted derivatives. The doped electronic conductive polymer makes it possible to reduce the protons of a solution as is shown by curve (1) of the attached Fig. 2. (Fig. 2)
