High Temperature Stability of Silver Based Porous Nanocomposites for Electrochemical Devices
High temperature (>550°C) applications of silver based porous composites have been limited due to relatively low melting temperature (962°C) of Ag. Incorporation of oxide particles was demonstrated as an effective approach for stabilization of the porous Ag microstructures. This study aims developing an understanding based on the relationships between the properties of the incorporated YSZ (yttria-stabilized zirconia), the developed porous microstructures and the electrochemical response of their electrodes. Minimum degradation was observed with the composite microstructure based on comparable Ag and YSZ particle sizes. The results demonstrated that YSZ incorporation into Ag matrix can increase the stable application temperature to 800°C.
