Alternate Matrix Material for Molten Carbonate Fuel Cell Electrolyte Structures

Abstract

The preparation and physicochemical characteristics of SrTiO//3 crystallites suitable for use as the matrix for liquid alkali carbonates in fuel cells are presented. The preparation utilizes a fugitive molten alkali chloride solvent to effect product formation. The product, following separation from the reaction medium, is composed of submicron, relatively uniformly shaped and sized, monodispersed crystallites. Data are presented on the utilization of this material in both hot-pressed and impregnation fabricated electrolyte structures. Data from the preliminary fuel cell evaluation of such structures are also presented.
