1. A method of making a solid oxide fuel cell, comprising:

  • providing a structure comprising a porous first ceramic layer, a porous second ceramic layer and a third ceramic layer electrolyte having a lower porosity than the first and the second ceramic layers;

    infiltrating an anode electrode catalyst into the porous first ceramic layer to form an anode electrode;

    infiltrating a cathode electrode catalyst into the porous second ceramic layer to form a cathode electrode, wherein the cathode electrode comprises a different material from the anode electrode;

    folding a portion of the third ceramic layer over a peripheral portion of the porous first ceramic layer to form a seal which prevents interaction of fuel and air; and

    placing the solid oxide fuel cell in a stack in which adjacent solid oxide fuel cells are separated by electrically conducting interconnects, wherein the stack is configured for power generation.
