Accelerated Testing Protocols For Solid Oxide Fuel Cell Cathode Materials

United States Patent Application

View the Complete Application at the US Patent & Trademark Office
Accelerated testing protocols that can be utilized for determining and projecting the durability of SOFC cathodes are described. The accelerated testing protocols can be carried out under simulated operation conditions so as to provide in a matter of a few hundred hours data that can correlate to the condition of the cathode following operation of the cell over the course of a typical operation life span of several thousand hours. A testing protocol can include cycling a SOFC from OCV to operating potential at a predetermined current density. Each cycle can be relatively short, for instance less than one minute.
