  • Production of a securely adhering, hydrophobic catalyst layer
    Publication number: 20050245389
    Abstract: The invention relates to a process for producing a catalytic component on a metallic or ceramic support for a fuel cell system, in which the catalytic component is applied to the metallic or ceramic support in at least one layer. This at least one layer contains at least one hydrophobic material component, which is applied together or alternately with at least one catalytically active material component in one process step. The invention also relates to a catalytic component, which is applied to a metallic or ceramic support, for a chemical reactor in a fuel cell system, and to methods of using the catalytic component.

  • Electrode capable of storing hydrogen and a method for the production of the same
    Patent number: 6887621
    Abstract: An electrode and a method of manufacturing an electrode with a capacity to store hydrogen, has a metallic substrate material to which an active compound is applied. The active compound is obtainable from a paste which comprises a dry fraction and a liquid fraction. The dry fraction comprises a mixture of a pulverulent storage alloy for hydrogen, soot and polytetrafluoroethylene (PTFE), the particles of the storage alloy being covered with PTFE in the manner of fibrils; and the liquid fraction comprising a mixture of water and a higher alcohol which has from 3 to 6 C atoms.
