However, the nano-column structure of the sputtered film on the nanoporous anodic aluminum oxide (AAO) substrate has been showing low performances, possibly originated from low in-plane electrical connectivity and limited reaction area at electrolyte\/electrode interface. We report here that application of 10&nbsp;nm thickness of Pt plasma-enhanced atomic layer deposition (PEALD) on the nanoporous Ni-based anode and Gd doped ceria (GDC) deposited by sputtering dramatically enhances anodic reactions, significantly reduces ohmic and polarization resistances (25% reduction in ohmic, 50% reduction in polarization resistances), and improves the power density over 60% compared to the bare cells. It is noteworthy that Pt PEALD deposited on the nanoporous GDC layer shows much-improved performance compared to that deposited on the nanoporous anode structure. This is attributed to the enhanced contact area at Pt\/GDC interface by exceptional conformal deposition of Pt PEALD and improved reaction sites from surface of GDC anode interlayer.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Wonjong Yu1, Sanghoon Lee, Sangbong Ryu, Chunhua Zheng, Gu Young Cho#, Suk Won Cha# Abstract Thin-film electrode deposited by sputtering has drawn attention due to high surface area and density of reaction sites for low-temperature solid oxide fuel cells.
