Embodiment Construction

[0016] In the high-temperature fuel cell shown schematically in FIG. 1 , electrode reactions take place, generating an electric current 1 , a reduction reaction in the anode layer 1 a as part of the support structure 1 ; an oxidation reaction at the cathode 3 , which is produced by The electrochemically active electrode layer 3a and the second partial layer 3b are formed. The larger part 1b of the carrier structure 1 is formed by a porous, gas-tight network system. Hydrogen and carbon monoxide constituting the gaseous fuel produce water and carbon dioxide on the anode layer 1a. At the cathode 3, molecular oxygen from a second gas stream (e.g. air) reacts to form O 2- , and at the same time electrons are taken from the metal conductor 40 connected with the electrode 4 . Oxygen ions pass through the solid material electrolyte 2 constituting a thin and airtight sintered electrolyte layer. This electrolyte layer separates the two electrode layers 1 a and 3 a in a gas-tight mann...

Abstract

A high-temperature fuel cell comprises a fuel side carrier structure which includes an anode layer composed of non-uniform phase, and the non-uniform phase comprises big holes and cavities with the form of micropore. The non-uniform phase comprises two parts of phase, the first part of phase is composed of ceramic material and the second part of phase comprises the metal which can complete the whole oxidation-reduction period of the reduction and supplementary oxidation reaction. The first part of phase is composed of big-and-small ceramic particles, and these particles form the inner-stable island ''burr particles'' in the non-uniform phase. The second part of phase generates the conductive connection traversing the carrier structure when the reduced metal exists. The average diameter (d50) of the large and small ceramic particle are respectively greater than 5 mu m and less than 1 mu m. The number ratio of these ceramic particles is selected with the following mode: combining the ''burr particles'' namely forming the ''viscous burr complex'' thereby stabilizing the carrier structure to prevent the variation of the stability.

Description

technical field [0001] The present invention relates to a high-temperature fuel cell with a carrier structure, which includes the anode layer on the fuel side according to the preamble of technical solution 1, and also relates to a method in which the electrolyte layer is made into a carrier, and the A high temperature fuel cell in which an anode layer is applied on the electrolyte layer. The invention also relates to a method of manufacturing such a fuel cell. Background technique [0002] From the non-previously published EP-A-1343215 (=P.7183) it is known a solid oxide (SOFC) fuel cell with a fuel-side support structure constituting the anode substrate, which acts as a membrane Carrier for electrolyte and cathode. At the so-called triple point (nickel / solid electrolyte / gas) that is the contact area between the anode and the electrolyte as a thin layer of the support structure, an electrochemical reaction takes place in which the nickel atoms are absorbed by the oxygen i...
