1. A solid oxide fuel cell, comprising:

  • a solid oxide electrolyte;

    a cathode electrode over a first major surface of the solid oxide electrolyte;

    an anode electrode over a second major surface of the solid oxide electrolyte opposite the first major surface; and

    an electrolyte reinforcement layer over a portion of at least one of the first major surface and the second major surface of the solid oxide electrolyte, the electrolyte reinforcement layer comprising a ceramic material and at least one of a metal and a metal oxide sintering aid;

    wherein the electrolyte reinforcement layer comprises yttria-stabilized zirconia (YSZ), alumina and the sintering aid selected from Ti, Mo, W, Mg, Hf, Rh, Co, Ni, Fe, Mn, Cu or Sn metal or an oxide of Ti, Mo, W, Mg, Hf, Rh, Co, Ni, Fe, Mn, Cu or Sn.
