Multi-phase CFD Fuel Cell Models with Lattice Boltzmann Method Implementation for High Current Density Operation in PEMFCs
The objective of this research is to develop a multi-scale/multi-dimensional model-based design tool to aid in the development of a fuel cell stack and electrochemical cells with enhanced performance at high current densities.
Using CFD to Understand the Transport and Corrosion Phenomenon inside High Temperature Molten Salt Systems for Next Generation Concentrated Solar Power Systems
The objective of this project is to investigate mass transfer in high temperature molten salt system along with corrosion in the systems. Coupling of non-isothermal experiments with CFD modeling of systems with thermal gradients and natural convection will allow enhanced evaluation of corrosion on samples.
Effect of Contaminants on the Performance of a Proton Exchange Membrane Fuel Cell
This Project is about the effect of the balance of plant contaminations on the fuel cell performance. In this project we are working on the impact of different contamination on the fuel cell performance and trying to develop a mathematical model that can show the effect of different contamination mechanisms on fuel cell performance.
Transport Studies and Modeling in PEM Fuel Cells
The overall objective of this project is to develop a better understanding of transport phenomena in current H2 Air polymer electrolyte membrane fuel cells. Water transport and its role in fuel cell performance is the main focus of this project. The project objectives have been achieved by generating custom materials; membranes, catalyst layers, diffusion media and flow fields and characterizing them ex situ, followed by operation in a fuel cell and modeling of the results.
The effect of metal oxide supports on the activity of Bimetallic Electrocatalysts towards methanol electrooxidation
Characterization of Gas Diffusion Layer and Their Effects on PEMFC Performance
The objective of this project is to describe polymer electrolyte membrane fuel cell (PEMFC) behavior resulting from changes in the fundamental properties of GDLs. This objective is being accomplished by measuring the GDL properties, including micro and macro porous layers, fuel cell performance under a variety of operating conditions, and by developing a mathematical model.
