Patent ID: 7927757

Claim:
A high temperature fuel cell comprising: a first cell formed by an anode and a first protonic conduction ceramic electrolyte in contact with one another, a second cell SOFC type, formed by a cathode and a second anionic conduction ceramic electrolyte in contact with one another, and a bonding layer positioned between the first and the second electrolyte, this bonding layer ensuring a union between the first and the second electrolyte, this bonding layer being based on a porous material and having three phases comprising: a protonic oxide phase comprising BaCeO3, or BaZrO3 or SrCeO3; an anionic conduction oxide phase comprising YSZ or cerine/gadolinium composite; and a porous phase for water evacuation, these three phases percolating in the bonding layer, said bonding layer playing the role of cathode for the first cell and the role of anode for the second cell.
