The phase evolution, electrical stability and chemical compatibility of sealing glass–ceramics for solid oxide fuel cell applications: effect of La 2 O 3 or CeO 2
In spite of the fact that rare earth oxides can improve the sealing properties of glass–ceramics, the electrical stability of these glass–ceramics under Solid Oxide Fuel Cell (SOFC) operational conditions still remains ambiguous. In this work, the electrical stability of glass–ceramics doped with La...

. In particular, the relationship between the phase evolution and the change in conductivity of glass–ceramics has been clearly demonstrated. Moreover, the sealing glass–ceramics show good chemical compatibility with 8 mol% yttria-stabilized zirconia (8YSZ) electrolyte, after being held at 750 °C for 1000 hours.
