Zusammenfassung:A solid oxide fuel cell (SOFC) that includes an anode electrode, a cathode electrode and a solid oxide electrolyte having a fuel inlet riser opening and a fuel outlet riser opening. The electrolyte is located between the anode electrode and the cathode electrode. The SOFC also includes a ceramic support layer on the electrolyte. The ceramic support is layer located around the at least one of a periphery of the electrolyte or at least partially around perimeters of the fuel inlet and fuel outlet riser openings. The ceramic support layer comprises a multi-component material comprising yttria stabilized zirconia (YSZ) and alpha alumina.
