Novel Electrode Design for Low Temperature Direct-Hydrocarbon Solid Oxide Fuel Cells

Description:

Reference #: 00808

The University of South Carolina is offering licensing opportunities for a Novel Electrode Design for Low Temperature Direct-Hydrocarbon Solid Oxide Fuel Cells

Invention Description:

Among the perovskite-type cathode materials for SOFCs, cobaltite has the highest surface oxygen exchange coefficient, oxide ion conductivity as well as electronic conductivity at reduced operating temperatures. These are the factors favorable for oxygen reduction reaction for a high performance cathode material. In order to overcome the barriers of thermal expansion mismatch as well as chemical interdiffusion issues, a novel cathode architecture using a composite of the cobaltite catalyst and the electrolyte material are proposed.

Potential Applications:

For the production of more efficient fuel cells

Advantages and Benefits:

(1) Superior thermal cycling capability

(2) Enhanced oxide ion conductivity.

(3) High cathode electronic conductivity and electrocatalytic activity

(4) Mitigated thermal mismatch on the cathode

(5) Superior electronic and ionic conductivity for the anode

(6) Direct utilization of hydrocarbon fuels without deactivation in the Ni-based anode.
