An open-source two-phase non-isothermal mathematical model of a polymer electrolyte membrane fuel cell
DownloadSpring 2014
A comprehensive open-source two-phase non-isothermal MEA model including the microporous layer and accounting for multi-step reaction kinetics for the ORR and HOR is developed for the first time. The model is integrated into openFCST, an open-source FEM based fuel cell simulation framework. All...

Fall 2011
High aspect ratio microelectromechanical structures have been found, in the literature, to collapse due to capillary forces of liquids. In this dissertation, mathematical models are developed to study (i) the collapse of a microstructure represented by a double cantilevered beam (DCB) with a free...

Mathematical modeling and experimental validation of thin low platinum content and functionally graded cathode catalyst layers
DownloadFall 2014
Low catalyst content remains a key requirement for the commercialization of polymer electrolyte fuel cells (PEFCs) into the energy, transportation, and material handling sectors. Understanding the fundamental phenomena reducing fuel cell performance at various stages of operation play a major...

Fall 2013
Recently there has been great research interest in small soft particles because of their significance in both biology and industry. The term ‘particle’ here is defined as a deformable object with size in the range of nano- to micrometers. Many experimental efforts have been spent on investigating...

Modelling of PEMFC Catalyst Layer Mass Transport and Electro-Chemical Reactions Using Multi-scale Simulations
DownloadFall 2014
The focus of this work is on improving understanding of mass transport limiting phenomena occurring within the micro-structure of Polymer Electrolyte Fuel Cell (PEFC) Catalyst Layers (CL). Micro-scale models, namely agglomerates, are employed within multi-scale CL framework, to examine many...
