DESCRIPTION

A metal oxide particulate membrane is made more electrically conductive, and thus more suitable for electrochemical cells by incorporation into the membrane of a dopant element. The dopant is dissolved in an alcohol and then incorporated in the sol-gel process used to form the particulate metal oxide membrane. The invention is exemplified by a niobium doped titanium dioxide ceramic membrane which has good porosity while having a conductivity several orders of magnitude higher than a similar membrane made without incorporating the niobium dopant

STATUS: U.S. Patent No. 5,028,568
