Exsolution of nano metal particle on anode for increased performance at low temperature operation

研究成果: Chapter in Book/Report/Conference proceedingConference contribution

抜粋

Spinel oxide (CuFe2O4) has been studied as anode for solid oxide fuel cells. Although CuFe2O4 spinel structure was decomposed by reduction atmosphere observed by SEM-EDX, TEM-EDX and XRD, the decomposed CuFe2O4 became metallic phase with the exsolved nano size alloy particles, which were composite of Cu rich Cu-Fe and Fe rich Fe-Cu metal on anode. According to power generation properties, alloy anode formed from CuFe2O4 showed the maximum power density (MPD) of 611 mW/cm2 at 1073 K and 101 mW/cm2 at 873 K. Comparing to Ni-Fe (9:1 wt.%) alloy anode, alloy anode from CuFe2O4 reduction showed significantly decreased anodic polarization resistance, which was measured by impedance spectroscope and so high power density was assigned to nano alloy particles.
