Polymer electrolyte fuel cells (PEFCs) operate with a ternary mixture of fuel and reactants. The majority of numerical models in the literature, including the in-house Open-source Fuel Cell Simulation Toolbox (OpenFCST) software, use Fick’s law of diffusion which is only valid for binary...
An open-source two-phase non-isothermal mathematical model of a polymer electrolyte membrane fuel cellDownload
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...
Mathematical modeling and experimental validation of thin low platinum content and functionally graded cathode catalyst layersDownload
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...
Modelling of PEMFC Catalyst Layer Mass Transport and Electro-Chemical Reactions Using Multi-scale SimulationsDownload
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...
