Scott Institute Student Seminar

Please join us for our third research talk series. Lunch will be provided.

+++

At CMU’s Electrochemical Decarbonization Lab, Jessy Ha, Eugene Jeong, and Corinne Smith are focused on improving the methods, materials, and characterization tools used for electrolyzers and fuel cells and understanding how different transport phenomena are impacted through novel designs. In this seminar, they will present work related to vapor deposition of thin materials, creating diagnostic tools for performance measurement, and using x-ray scattering to characterize polymers that are used in electrolyzer fabrication. .

Jessy Ha is a first year PhD student in MechE. During her MS and first semester of PhD, her work has been focused on polymer electrolyte water electrolyzer catalyst materials, specifically, chemical vapor deposition of anode catalysts to create thin films. Currently, she is also researching catalyst inks to see how different parameters for the ink recipe affects electrolyzer performance.

Eugene Jeong is a first year PhD student in the mechanical engineering department. In his first year, he is looking at sizing particles in solution by small angle x-ray scattering. In particular at ionomers - polymers with ionic groups - which are useful for fabricating films used in electrochemical devices such as fuel cells and water electrolyzers.

Corinne Smith is a first year PhD student in the CMU electrochemical decarbonization lab (EDL). Her research has been focused on water electrolyzers, which are devices used to generate low-carbon hydrogen gas from water and electricity. Her project has been designing a diagnostic tool to create a voltage profile across the membrane of a water electrolyzer, which provides insight into gas distribution and crossover. Cells with high gas crossover pose a safety hazard, which is why it is useful to have a tool that can measure the gas crossover within the membrane and inform future designs for safer water electrolyzers.
