Electrochemical Energy Conversion Systems

Design, modeling, and validation of batteries, fuel cells, electrolyzers, and catalytic systems. We bridge fundamental electrochemistry with device-level engineering to de-risk performance, durability, and scale-up.

Selected Projects

With over 10 years of experience in electrochemical energy conversion and advanced materials engineering, the projects below highlight representative work spanning fuel cells, electrolyzers, batteries, and membrane systems.

Nanobubble-Enabled Thin Films & Spun Fibers (Patented Technology)

Invented and patented novel fabrication methods incorporating nanobubbles during thin-film coating. These approaches enabled controlled pore architectures and enhanced mass transport, yielding performance benefits across PEM fuel cells, PEM water electrolyzers, lithium-ion battery electrodes, and ultrafiltration membranes. Patent: US20250113651A1

Nanobubble-Enabled Spun Fibers (Patented Technology)

Comparing the electrochemical performance and structural differences of nanobubble-treated fibrous iridium oxide made using electrospinning. It was found that NB-treated samples generate smaller fibers on average with higher overall surface area, resulting in better in electrochemical performance. Patent: US20250257497A1

Feedwater Chemistry & Dissolved Gas Effects in PEM Electrolyzers

Investigated the influence of dissolved gases and operating conditions on PEM water electrolyzer performance and durability, linking feedwater chemistry to efficiency, degradation behavior, and operational best practices.

PGM-Free Catalysts for Direct Methanol Fuel Cells

Evaluated platinum group metal-free catalyst systems in direct methanol fuel cells using a custom reference electrode architecture to decouple anode and cathode behavior and identify mechanistic performance limitations.

Electrokinetics of Vapor-Fed Methanol Oxidation in DMFC Anodes

Tested and characterized the electrokinetics of vapor-fed methanol oxidation reactions in DMFC anodes, providing insight into transport and reaction mechanisms for next-generation fuel cell architectures.

Pore Network Modeling of PEM Water Electrolyzer PTLs

Two-phase pore network simulation comparing water and oxygen transport in a PEM water electrolyzer between a fiber-based titanium porous transport layer (PTL) and a sintered powder PTL. It was found that The Ti fiber PTL has better overall single-phase transport properties, however it takes a larger loss during multi-phase transport, especially at high current density.

Advanced Energy Community Modeling – Huntington Beach, CA

Supported a CEC-funded community energy retrofit through battery dynamic modeling, solar generation estimation, and energy balance analysis, with demand modeling informed by OpenStudio simulations and on-site energy data logging.
