The invention relates to a fuel cell-support built up of a ceramic having a composition of from 35 to 80% by weight of MgO, from 20 to 65% by weight of Al2O3 and from 0 to 15% by weight of impurities and/or further inorganic aggregates and possessing a coefficient of thermal expansion in the range from 9 to 13 . 10<-6> K<-1>, measured in a temperature range from 20 to 1000@C. The invention further relates to a solid-electrolyte high-temperature fuel cell comprising an active unit and a support having the properties already mentioned above, the active unit being built up of a solid-electrolyte layer which is preferably coated on the anode side with a layer of a ternary mixture of nickel, zirconium dioxide and cerium and on the cathode side preferably with a strontium-doped layer of LaMnO3. A process for manufacturing a fuel cell is also given. |
