Solid Oxide Fuel Cells have the highest energy conversion efficiency among fuel cells. To facilitate the hydrogen reduction reaction at the anode, high surface area with high density of triple phase boundaries (TPB) is required. My work focuses on increasing the reaction surface area (i.e. TPB) without compromising ionic and electronic conductivity of the anode layer. I employ vapor–liquid–solid (VLS) growth, hydrothermal synthesis, and micro-/nano-molding for my fabrications. As materials, YSZ and GDC are used. Material characterization uses XRD, SEM, and Raman spectroscopy and electrochemical performance of cells are assessed via current–voltage measurements and impedance spectroscopy.
