Bipolar plates
Metallic bipolar plates (BPPs) offer high strength and easy manufacturability for PEM fuel cells but suffer from corrosion and rising interfacial contact resistance (ICR) under acidic operating conditions. To overcome these limitations, MOF-COF hybrid coatings are developed as multifunctional protective layers. These hybrids provide (i) strong coordination to stainless steel for excellent adhesion, (ii) tailored pore chemistry to trap corrosive ions, and (iii) continuous π-conjugated pathways that enhance through-plane and in-plane conductivity.

Functional Bio-Nano Materials: Developing advanced biomimetic surface technologies that enhance the durability and performance of metallic components used in Proton-exchange membrane fuel cell (PEMFC). By taking inspiration from natural surfaces that maintain stability under harsh environmental conditions, we combine experimental surface engineering with multi-physics simulation to understand how fluid interactions, surface architecture, corrosion processes, and mechanical stresses influence long-term material behavior. Using a combination of laboratory testing and COMSOL-based modelling, our work aims to identify and optimize surface structures that resist degradation, manage interfacial phenomena, and maintain functionality under demanding operating cycles. This integrated experimental computational approach helps guide the design of next-generation, high-performance materials for emerging energy applications.
