To expand the processing options for low-temperature-operating solid oxide fuel cells (LT-SOFCs), the hybridization of powder processing and vacuum deposition is attempted. Nanostructured nickel-yttria-stabilized zirconia (Ni-YSZ) anode functional layer (AFL) and YSZ/gadolinia-doped ceria (GDC) bi-layer electrolyte are fabricated over a sintered anode support by pulsed laser deposition (PLD), a physical vapor deposition technology. The most common powder-processed (screen-printed and sintered) La0.6Sr0.4Co0.2Fe0.8O3-delta-Gd0.1Ce0.9O1.95(LSCF-GDC) composite cathode is applied over vacuum-deposited thin-film components. When LSCF-GDC is sintered at a general sintering temperature of 1050 degrees C then the continuity of the GDC buffer is lost and excessive interdiffusion between the cathode and the electrolyte has occurred at the interface. On the other hand, if the sintering temperature is lowered to 950 degrees C, peak power density more than 1.7 W cm(-2) at 650 degrees C is obtained. Moreover, the operation stability of the hybrid SOFC (degradation rate similar to 8%/000 h) is superior to that of the SOFC with a vacuum-processed nanostructure cathode (degradation rate similar to 21%/100 h) when exposed to 0.7 A cm(-2) at 650 degrees C, which is a significantly harsh degradation test condition for LT-SOFCs.
