20080261098 | PROTON-CONDUCTING MEMBRANES FOR ELECTROCHEMICAL DEVICES, AND RELATED ARTICLES AND PROCESSES - A method for making a proton-conducting membrane is described. The method includes the steps of combining a protonated, layered inorganic material with a proton-conducting organic polymer in a liquid medium; exfoliating the layered inorganic material, so that individual layers of the inorganic material are suspended in the liquid medium and spaced from each other; and the polymer is absorbed onto the surface of the individual layers. In this manner, a polymer-inorganic composite is formed. The liquid can then be removed, to recover the resulting membrane. Related electrolysis and fuel cell devices are also described, which incorporate the proton-conducting membrane. | 10-23-2008 |
