Catalyst and method for its manufacture

A superconductor and a method of producing the same include a supporting substrate and a superconducting oxide ceramic material applied to the supporting substrate. At least one thermally and chemically stable intermediate layer is applied directly between the superconducting ceramic material and the substrate.

Superconductor and method for its production

An electrochemical measuring cell, in particular for the determination of the oxygen content in gases, which has an ion-conducting, solid electrolyte. The latter is provided with at least one electrode in the form of a porous layer containing electron-conducting, ceramic oxide material. For the improvement of the electron-conductivity of the electrode there is embedded in the layer metallic material such as a metal wire whose electron-conductivity is greater than the electron-conductivity of the oxide material. Only as much metallic material need be added to increase the electron-conductivity of the electrode sufficiently to a predetermined value.
