  • Method for producing electrode composite material
    Patent number: 8586139
    Abstract: An object of the present invention is to simplify the process of producing an electrode composite material. Disclosed is a method for producing an electrode composite material, comprising the steps of: preparing a material comprising Li, La, Ti and O and heating the material, wherein the composition ratio between Li, La and Ti of the material is in the range of a triangle having three vertices at LiO0.5:LaO1.5:TiO2=23:24:53, LiO0.5:LaO1.5:TiO2=5:36:59 and LiO0.5:LaO1.5:TiO2=8:28:64 in the LiO0.5—LaO1.5—TiO2 triangular diagram.
    Type: Grant

  • Metal alloy catalysts for fuel cell cathodes
    Patent number: 8334081
    Abstract: For the oxygen reduction reaction at the cathode of proton exchange membrane fuel cells, a metal alloy catalyst contains the metals Pd, M1 and M2 where M1 and M2 are different metals selected from Co, Fe, Au, Cr and W (but excluding the combination PdCoAu). Preferred ternary alloys for use as catalysts may be selected from PdCoCr, PdCoW, PdFeCr, PdFeW, PdCrW, PdWAu, PdCrAu, PdCoFe and PdFeAu. Compositional ranges that are specially effective are assessed by a high throughput physical vapor deposition method. Catalysts especially suitable for use in direct methanol fuel cells are identified.
