Zusammenfassung:	A method for determining the oxygen surface exchange property of a material in a solid oxide fuel cell. The method begins by first receiving a data stream comprising of continuous weight measurements of the material and time measurements of when the continuous weight measurements of the material are taken. While receiving the data stream an oxygen concentration test is performed which involves: flowing a primary gas flow onto the material while simultaneously increasing the temperature of the primary gas flow to a set temperature, flowing the primary gas flow onto the material at the set temperature, and stopping the primary gas flow and starting a secondary gas flow at the set temperature. This data stream is then displayed analyzing the weight change of the material over time.
