| Abstract: | A novel in situ co‐assembled nanocomposite LSM‐Bi1.6Er0.4O3 (ESB) (icn‐LSMESB) was obtained by conjugated wet‐chemical synthesis. It showed an enhancement of the cathode polarization at 600 °C by >140 times relative to conventional LSM‐Y0.08Zr0.84O1.92 (YSZ) cathodes and exceptional solid oxide fuel cell (SOFC) performance of >2 W cm?2 below 750 °C. This demonstrates that this novel cost‐effective and broadly applicable process provides new opportunities for performance enhancement of energy storage and conversion devices by nanotailoring of composite electrodes. |
