Optimization of Microporous Layer (MPL) for Reduction ofIridium Loading in Proton-Exchange Membrane WaterElectrolyzers

Objectives
Validate the outcomes of the modeling/simulation with experimental data (referring to previously accomplished experiments or the ones which are being performed currently)

Assess the fundamentals of the Proton Exchange Membrane Water Electrolyzer (PEMWE) and scrutinize the phenomena and
parameters involved in the PEMWE during OER process.

Mathematical modeling and simulation of the PEMWE by optimization of MPL with the identification of key parameters

Expected Outcomes
The anticipated outcomes of this research are significant and far-reaching. The introduction of Microporous Layer (MPL) in Proton Exchange Membrane Water Electrolyzers (PEMWE) is expected to enhance or maintain performance while utilizing minimal iridium loading. Given that iridium is a rare and expensive element, achieving comparable or improved PEMWE efficiency with reduced iridium content holds the promise of substantially lowering production costs. This, in turn, has the potential to make PEMWE more economically viable at an industrial scale, fostering widespread adoption of the technology. The economic feasibility resulting from reduced iridium usage can contribute to large-scale PEMWE production, supporting the global shift towards carbon neutrality.

About Myself:
In addition to my work with the Green Hydrogen Lab, I find joy in the simple pleasures of life.
During my free time, you’ll often find me immersing myself in the world of music, as I enjoy
noodling on my guitar. It’s not just a hobby; it’s a creative outlet that allows me to unwind and
express myself. Equally, I am a movie enthusiast and series buff. Whether discovering new
releases or revisiting classics, I appreciate the art of storytelling. In fact, some of my most
cherished moments involve rewatching favorite movies, holding a special place in my heart, with
my wife. After 12 years in the U.S., returning to Nepal has sparked a new passion for adventure,
particularly in hiking and trekking. The diverse landscapes of Nepal offer an exciting playground
for exploration, and I’m eager to embrace more adventures in the coming months. Rediscovering
the natural beauty of my home country has become a thrilling chapter in my journey post-return.
