Patent ID: 7931990

Claim:
A fuel cell component comprising: a cathode comprising a lanthanum manganate material, the cathode having channels for receiving a flow of oxygen, and a buffer layer disposed within the channels as a continuous coating of material having a finite thickness, filling a fraction of the total volume of the channels, and defining an interior surface of the channels through which oxygen flows; an anode comprising channels for receiving a flow of fuel; and an electrolyte layer disposed between the cathode and the anode; wherein the buffer layer comprises a two-phase material; and wherein the buffer layer comprises a material selected from the group consisting of Ni—NiO, Fe 3 O 4 —Fe 2 O 3 , Mn 3 O 4 —Mn 2 O 3 , Mn 2 O 3 —MnO 2 , Cu—Cu 2 O, and Mn 3 O 4 —(La 1-x A x ) y MnO 3-δ , wherein “A” designates a dopant material substituted on the A-site of the perovskite crystal structure, wherein “x” represents the amount of dopant substituted for La within the structure, wherein “y” represents the percent occupancy of atoms on the A-site within the crystal lattice.
