ABSTRACT:
Utilizing an organometallic precursor, a metal oxide is formed within the pores of a porous sintered blank substantially uniformly throughout the porosity of the blank producing a porous bubble pressure barrier of predetermined pore size. The barrier is integrally sintered to a face of an electrode, the median pore size of the barrier being significantly smaller than that of the electrode, producing a composite useful as an electrode in a molten carbonate fuel cell. The blank and the electrode are composed of metal.
