A cathode in a solid oxide fuel cell containing AgPrCoO. The operating temperature range of the cathode is from about 400&#xb0; C. to about 850&#xb0; C.

Solid oxide fuel cell cathode materials

A solid oxide fuel cell comprising an anode layer, an electrolyte layer, and a two phased cathode layer. The two phased cathode layer comprises praseodymium and gadolinium-doped ceria. Additionally, the solid oxide fuel cell does not contain a barrier layer.

Cathode for solid oxide fuel cells

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 degradation gas flow onto the cathode material while simultaneously increasing the temperature of the primary gas flow to a set temperature, flowing the degradation gas flow onto the material at the set temperature, stopping the degradation gas flow and starting a primary gas flow at the 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.

Evaluation of solid oxide fuel cell cathode materials

A method of producing an infiltrated solid oxide fuel cell (SOFC) layer. The method begins by infiltrating a solution containing a solute into a SOFC layer to produce a primary SOFC layer. The primary SOFC layer is then dried in a heated environment, wherein the heated environment ranges in temperature from about 25&#xb0; C. to about 100&#xb0; C. to produce a dry primary SOFC layer. The dry primary SOFC layer is then cooled at a rate less than about 5&#xb0; C./min to room temperature to produce a cooled primary SOFC layer. The cooled primary SOFC layer is then heated to a temperature greater than 500&#xb0; C. then quenching to a temperature from about 10&#xb0; C. to about 30&#xb0; C. to produce an infiltrated SOFC layer.
