Area of Work

    During the course of my doctoral research at the University of Pennsylvania, I studied various molten metal - metal oxide systems as anodes to enable the utilization of solid carbonaceous fuels, like coal and renewable biomass, in solid oxide fuel cells (SOFC). I demonstrated solid fuel utilization and achieved performance levels on par with state-of-the-art H2-fuelled SOFC using molten antimony as the anode. The experimental setup involved cathode-electrolyte bilayer fabrication by ceramic tape casting and the cell performance was analyzed by V-i polarization curves and electrochemical impedance spectroscopy. Fuel - metal oxide reactivity tests were carried out in flow reactors and the products were analyzed by mass spectrometry. Reaction phases formed in the cell were characterized by x-ray diffractometry and scanning electron microscopy using energy dispersive spectroscopy. At the University of Calgary, my first postdoctoral appointment was focused on the development of carbon and sulfur tolerant anodes for SOFC that utilize reformed natural gas or diesel as fuel. The goal of my current postdoctoral appointment at EERG involves the design of experiments (DoE) for the fabrication and development of cheap solid sorbent materials for CO2 capture in power-plant flue gas streams. Writing research proposals for project funding and mentoring graduate and undergraduate students are also a significant focus.
