| Abstract Scope |
The commercialization of energy efficient solid oxide cell (SOC) technology is challenged by the fast degradation of performance. To address this challenge, lowering the operating temperature is critical. To achieve reduced temperature, SOC must utilize high-performance materials, reduced thickness of electrolyte and novel microstructure with abundant reactive sites. In this presentation, we show fabrication of two types of thin-film electrolyte SOCs on a porosity-graded substrate: asymmetrical and symmetrical. Asymmetrical cells are directly fabricated from the “single step” phase inversion method to which air electrode and fuel electrode are applied by screen printing and infiltration, respectively. Symmetrical cells are fabricated by integrating two asymmetrical substrates by “face-to-face” infusion. The air electrode and fuel electrode nanoparticles are incorporated into the two porosity-graded microstructures through the infiltration process. Due to the ultrathin electrolyte and high surface area of electrocatalysts, we show that the performance of these phase-inversion derived SOCs at reduced temperatures. |
