• Facilitated fundamental research supporting FCE’s first joint project with ExxonMobil Research & Engineering using molten carbonate fuel cells for CO2 capture.• Designed and implemented electrochemical experiments that revealed a drastic change in cathode mechanism unique to this application• Greatly improved cell and stack-level performance and stability through engineering the cathode, electrolyte, and current collectors• Identified the rate-limiting phenomena using a physics-based electrode model with Python• Highlighted results and data analysis in weekly presentations and technical reports both internally and to ExxonMobil• Analyzed the electrochemical performance of surface-coated solid oxide fuel cell cathodes via impedance spectroscopy to characterize and understand drivers for degradation

Seattle, Wa, Us

• Analyzed thin film (< 70 nm) solid oxide fuel cell microelectrodes, isolating surface phenomena from the bulk.• Assessed the long-term stability and degradation mechanisms of state-of-the-art porous oxygen electrodes.• Designed novel hardware and software platform for simultaneous global nonlinear impedance and local scanning probe microscopy measurements.

Seattle, Wa, Us

• Studied mixed ionic and electronic conducting electrodes for solid oxide fuel cells and electrolyzers.• Performed nonlinear impedance analysis on perovskite electrodes in both oxygen and hydrogen-water environments.• Developed nonlinear analytical and numerical multi-dimensional models capturing relevant kinetic, thermodynamic, and transport phenomena for these systems.• Designed, built, and performed a variation of coulometric titration for measuring minute changes in defect chemistry for oxides.
