Meeting 2017 TMS Annual Meeting & Exhibition
Symposium Energy Materials 2017: Materials for Energy Conversion with Emphasis on SOFC
Presentation Title Modified SOFC Cermet Anodes for Improved Catalysis at High Fuel Utilization

On-Site Speaker (Planned) Uday Pal
Abstract Scope This research analyzes the effects of various nickel infiltration (vapor and liquid phase) processes on the performance of anode-supported SOFCs over a wide range of hydrogen and water vapor partial pressures at intermediate temperatures (600-800 Celsius). The efficacy of various infiltration techniques, resulting density and location of the sub-micron size Ni deposits, impact of the increased three-phase-boundary (TPB) length, and the stability of the deposited Ni particles were examined through long-term and/or accelerated testing. Cell performance was measured using I-V and EIS techniques, and the anodic polarization losses were calculated using a validated full cell model. Anode microstructure including the location, size and distribution of the sub-micron size Ni particle deposits was characterized employing FIB, SEM and TEM. The results identify the role of the size and location of the sub-micron size nickel particles in enhancing the anode performance at high fuel utilization.
