Abstract

Extensive research has been performed on solid oxide fuel cell cathodes. These cathodes have a multitude of performance restrictions, such as stability in an oxidation environment, have sufficient electrical conductivity, and catalytic activity for the oxidant gas reaction at the appropriate operating temperature. Also the cathode must be chemically and thermally compatible with the other cell components from room temperature to the operating temperature and even to higher fabrication temperatures. Praseodymium strontium manganite (PSM) has shown promising electrical properties with respect to idealistic properties of cathodes in solid oxide fuel cells. Various dopant levels of strontium in the perovskite structure were investigated, which include Pr 1-xSr xMnO 3-δ where x = 0.10, 0.20, 0.30 and (Pr 1-xSr x) 0.98MnO 3-δ where x = 0.20 and 0.30. This cathodic material has shown electrical conductivity over twice as high as a traditionally used cathode material, La 0.8Sr 0.2MnO 3. Through this investigation, the electrical conductivities of this ceramic series were measured from 200°C to 950°C. Within the same temperature range the Seebeck coefficient was also investigated. This coefficient is a measurement of the change in voltage across a temperature gradient and thus can be referred to as its thermal power. This measurement provides a better overall understanding of the high electrical conductivity displayed within the material.
