Development of Novel Electrod for Proton Exchange Membrane Water Electrolyzer

The increasing global energy demand and the environmental impact of fossil fuels highlight the need for sustainable energy carriers. Hydrogen is a promising solution due to its high energy density and wide applicability; however, most hydrogen is currently produced through carbon-intensive processes. Water electrolysis powered by renewable electricity offers a low-emission alternative, with proton exchange membrane water electrolyzers (PEMWEs) being particularly attractive because of their high efficiency, compact design, and ability to operate under dynamic conditions. Despite these advantages, large-scale deployment of PEMWEs is limited by high costs, largely associated with the membrane electrode assembly (MEA), which governs efficiency and durability.
The MEA consists of a proton exchange membrane, catalyst layers, and porous transport layers (PTLs). Precious metal coated Titanium-based PTLs and precious metal based catalysts (such as iridium and platinum) are required to withstand the harsh anode environment, making cost reduction a key challenge. This project investigates hybrid MEA designs by controlling catalyst distribution between the membrane and PTL, along with advanced porous transport electrode concepts using Ir-based intermetallic phases on Ti PTLs. Electrolyzer testing and post-operation analyses will be used to link performance losses to degradation mechanisms, enabling more durable and cost-effective PEMWEs.
