Metallic interconnects, if successfully developed, offer significant performance and cost benefits for solid oxide fuel cells (SOFCs).  Present materials do not permit these advantages to be obtained.  This proposal promises a novel approach to obtain these benefits.  By selecting alloy compositions that offer a thermal expansion match and utilizing a coating to carry the current, a compliant metal interconnect can be developed.  A doped coating material with the desired conductivity and stability will be developed and optimized.  This will be tested ex-situ and in stack using a patent pending compliant interconnect design to verify the benefits.

 

Commercial Applications and Other Benefits as described by the awardee:  Phase I will enable the implementation of metal interconnect that simultaneously offer low cost, high power density and stability to SOFC stacks.  This will lead to SOFC stacks with the technical performance and commercial potential to be developed.
