Abstract:
Porous metal-supported solid oxide fuel cells (PMS-SOFCs) demonstrate potential to dramatically reduce their costs while simultaneously enhancing the durability of SOFCs. However, owing to the unsatisfactory performance improvement of PMS-SOFCs at low temperatures and available fabrication processes, their commercial applications are limited. In this study, exceptional performance of PMS-SOFCs for electricity generation at low temperatures (400–600 °C) with vacuum cold sprayed (VCS) nanostructured La0.6Sr0.4Co0.2Fe0.8O3?? (LSCF) as the high-activity cathode, the plasma-sprayed Ce0.8Gd0.2O2??/La0.8Sr0.2Ga0.8Mg0.2O3?? (GDC/LSGM) bilayer as the electrolyte, and a cermet consisting of the nickel–gadolinium-doped-ceria (Ni–GDC) composite as the anode. By carefully controlling the spray particle size, a nanostructured LSCF cathode is obtained, and the oxygen reduction reaction (ORR) is activated.
