The present invention relates to a protonic ceramic fuel cell, a cathode for a protonic ceramic fuel cell, and a method of making the same. More specifically, the cathode for a protonic ceramic fuel cell utilizes a phase-pure perovskite structure of the compound BaCo_0.4Fe_0.4Zr_0.2-xY_xO_3-delta., where x is between about 0 and about 0.2. The cathode material may then be utilized in a PCFC as either a thin film porous cathode or as nanoparticles infiltrated into a cathode bone having a different structure.

Low cost stable air electrode material for high temperature solid oxide electrolyte electrochemical cells

Patent Kuo, Lewis J. H. ; Singh, Prabhakar ; Ruka, Roswell J. ; Vasilow, Theodore R. ; Bratton, Raymond J.

A low cost, lanthanide-substituted, dimensionally and thermally stable, gas permeable, electrically conductive, porous ceramic air electrode composition of lanthanide-substituted doped lanthanum manganite is provided which is used as the cathode in high temperature, solid oxide electrolyte fuel cells and generators. The air electrode composition of this invention has a much lower fabrication cost as a result of using a lower cost lanthanide mixture, either a natural mixture or an unfinished lanthanide concentrate obtained from a natural mixture subjected to incomplete purification, as the raw material in place of part or all of the higher cost individual lanthanum. The mixed lanthanidemore »« less

Braze material for joining ceramic to metal and ceramic to ceramic surfaces and joined ceramic to metal and ceramic to ceramic article

Patent Hunt, Thomas K. ; Novak, Robert F.

An improved active metal braze filler material is provided in which the coefficient of thermal expansion of the braze filler is more closely matched with that of the ceramic and metal, or two ceramics, to provide ceramic to metal, or ceramic to ceramic, sealed joints and articles which can withstand both high temperatures and repeated thermal cycling without failing. The braze filler material comprises a mixture of a material, preferably in the form of a powder, selected from the group consisting of molybdenum, tungsten, silicon carbide and mixtures thereof, and an active metal filler material selected from the group consistingmore »« less
