ABSTRACT:
The present disclosure is directed to a fuel cell component having a cathode that includes a lanthanum manganate material as well as channels for receiving a flow of oxygen, and a buffer layer extending along the channels through which oxygen flows. The fuel cell component also includes an anode having channels for receiving a flow of fuel and an electrolyte layer disposed between the cathode and the anode.
