Symmetrical solid oxide fuel cells(SSOFCs)could be alternative energy conversion devices due to their simple fabrication process and low ***,perovskite La_(0.6)Ce_(0.1)Sr_(0.3)Fe_(0.95)Ru_(0.05O3-δ)(LCSFR)was synthesized and evaluated as a high-performance electrode for SSOFCs based on the electrolyte of La_(0.9)Sr_(0.1)Ga_(0.8)Mg_(0.2)O_(3-δ)(LSGM).LCSFR retains their stable perovskite crystal structure in both reducing and oxidizing atmospheres,though a minor amount of LaSrFeO4 phase is present under reducing *** investigation shows that homogeneously dispersed Ru metallic nanoparticles are exsolved on the surface of LCSFR after being *** polarization resistance(Rp)of LCSFR-CGO(Ce_(0.9)Gd_(0.1O2-δ))is about 0.11Ω·cm^(2)at 800℃in air,while the value of Rp for LCSFR-CGO in wet H_(2)(3%H_(2)O)increases up to 0.32Ω·cm^(2).The symmetrical LCSFR-CGOILSGMILCSFR-CGO cell demonstrates a performance with an open circuit potential(OCV)of 1.07 V and a maximum peak power density of 904 mW/cm^(2)at 800℃using wet H2 as the *** high performance indicates that LCSFR is a candidate electrode for SSOFCs.
