Organization: University of California at Berkeley

Grant Amount: $74,997

Grant Term: 12 Months

Project Description:

The purpose of this project is to research the feasibility of using a specially formulated composite anode layer on the thin ceramic electrolyte film in a solid oxide fuel cell. The anode layer will be low cost and tuned to the thermal expansion coefficient of the ceramic electrolyte film to permit rapid thermal cycling.

Proposed Outcomes:

· Prototype laboratory scale SOFC membranes constructed with composite anode layer.

· Feasibility analysis based on characterization and performance of prototype membranes to withstand rapid thermal cycling while maintaining a high power density (300 mW/cm²).

Anticipated Benefits:

· Increase the reliability of SOFCs used in distributed generation applications by making them capable of rapidly cycling from room temperature to an operating temperature of 850 ^oC.

· Reduce membrane cost to less than $65/sqft.
