School of Engineering Department of Mechanical and Aerospace Engineering 168 Department of Mechanical and Aerospace Engineering Power-Source-Free Energy Generator Supervisor: CHEN Sherry / MAE Student: ZHANG Yuchen / AE Course: UROP3100, Fall This semester’s work involves the experimental preparations for the design of Energy Conversion Module (ECM). Two major steps were taken into consideration at the beginning: the first was to use a CAD product to simulate the realistic operation of a CPU chip, while the next was to use phase-transforming material to obtain the data of generated electricity under simulative conditions provided by the CAD product. Since there was shortage in phase-transforming material, I was asked by Dr. Chenbo to investigate the material composition and therefore fabricate the material that suits best to ECM. The latter procedure will hopefully be accomplished by next spring, after which all requisites will be attained, and a prototype can then be manufactured. Power-Source-Free Energy Generator Supervisor: CHEN Sherry / MAE Student: ZHANG Yuchen / AE Course: UROP4100, Spring The energy conversion module (abbreviated to ECM)’s operation notably depends on the pyroelectric material. To ensure standard functionality and further enhance its performance, different compositions of pyroelectric materials were fabricated to prepare for the assembly of the ECM during the semester. Being suggested several candidate compositions, the subsequent preparatory works focused on their realization using available ingredients and equipment. At the end of the term, there were in total two pyroelectric material rods ready for characterization. In addition to the successful attainment of the required materials, hands-on experiences of laboratory work, including safety issues and the use of various instruments, were obtained. Electrochemical Characterization and Evaluation of Thin Film Cathodes for Solid Oxide Fuel Cells Supervisor: CIUCCI Francesco / MAE Student: CHAWLA Anhad Singh / SUSEE Course: UROP1100, Spring This progress report discusses the results of using a newmethod Ultra-fast High-Temperature Sintering(UHS) on symmetric cells and protonic ceramic fuel cells. BaFe0.9Zr0.1O3-δ(BFZ) and BaFe0.9Zr0.1O2.9-δF0.1(BFZ-F) are compared as cathodes to gauge the performance of Fluorine as a dopant. Optimal conditions and experimental procedures for UHS are established to reach sintering temperatures for the cathode. Symmetric cell area specific resistance is calculated via electrochemical impedance spectroscopy(EIS) and compared to traditional, furnace-sintered material. Fuel cell performance is currently being evaluated and future research directions are listed. UHS performance and benefits are discussed and avenues of improvement are identified.
