2010, Master of Science in Engineering (MSEgr), Wright State University, Materials Science and Engineering.
Solid Oxide Fuel Cell (SOFC) structures must be optimized for high performance, increased life, and low cost. Fabrication methods are an area of research interest in bringing down the total cost of SOFCs, and can also impact cell life and performance. Graded functional layers have been shown to enhance cell performance, but current fabrication methods require multiple fabrication steps. This thesis describes a novel fabrication method capable of compositional gradation of functional layers for SOFCs. Using colloidal spray deposition technology, a controlled co-deposition strategy was utilized to fabricate SOFC's with compositionally graded cathode and anode functional layers (CGCFL/CGAFL). In this research, compositionally graded CGCFL/CGAFL SOFCs were tested and analyzed using current-voltage measurements and energy impedance spectroscopy methods. Scanning electron microscopy and elemental mapping were utilized for structural characterization. The fabrication technique presented in this thesis allows for the rapid and precise, single-step deposition of a compositionally graded SOFC interlayer, and should facilitate the optimization of SOFC stack designs.
