Breaking the Wall of Cost-Effective Hydrogen fuel Cells

Breaking the Wall of Cost-Effective Hydrogen fuel Cells

Global Call 2026 Finalist Interview: Engineering & Technology

Yu Huang is the Traugott and Dorothea Frederking Endowed Engineering Chair and Professor in Materials Science and Engineering at UCLA.  Her research focuses on designing unique nanoscale materials for various applications. She has pioneered the bottom-up assembly of heterogeneous material structures, creating fundamentally new approaches for integrating dissimilar materials across multiple length scales, enabling advances in sustainable energy, electronics, photonics, and quantum materials. 

Which wall does your research or project break?  

Our research breaks the long-standing tradeoff between catalyst activity, durability, and platinum utilization in proton exchange membrane fuel cells (PEMFCs). For decades, improving catalytic activity has often come at the expense of stability, while increasing durability typically required larger platinum particles or higher platinum loading, making fuel cells prohibitively expensive. This fundamental materials limitation has been one of the greatest barriers to the widespread commercialization of hydrogen fuel cell technologies.


What is the main goal of your research or project?

By establishing heterogeneous interface engineering as a new catalyst design paradigm, we engineer the local chemical and structural environment surrounding platinum nanoparticles rather than simply modifying their composition. Through innovations such as graphene nanopockets, embedded oxide clusters, we stabilize ultrasmall platinum nanoparticles under realistic operating conditions while simultaneously enhancing catalytic activity. These discoveries overcome the conventional tradeoffs among performance, durability, and precious-metal loading, enabling catalyst lifetimes exceeding 200,000 hours under heavy-duty operating conditions.


What impact does your research or project have on society?

Breaking this barrier has broad implications for the hydrogen economy. By dramatically extending catalyst lifetime while reducing platinum requirements, our work provides a scalable pathway toward cost-effective, durable fuel cells for transportation, heavy-duty vehicles, and other industrial applications. More broadly, it establishes a general design principle for next-generation electrocatalysts, accelerating the deployment of clean hydrogen technologies and advancing global decarbonization efforts.

What advice would you give to young scientists or students interested in pursuing a career in research, or to your younger self starting in science?

Find something you are truly passionate about. Research is a long journey filled with setbacks, and genuine curiosity is what sustains you through the difficult moments. Don't just focus on solving the next problem—keep the bigger picture in mind. Ask yourself how your work can contribute to society and make the world a better place. Having a meaningful purpose will help guide your decisions and inspire perseverance.
Take ownership of your research. Don't simply execute someone else's ideas; develop your own scientific vision. Be willing to ask bold questions, challenge conventional thinking, and take responsibility for the direction and impact of your work. The most rewarding discoveries often come from pursuing ideas or resolve problems that others have overlooked.
Finally, remember that science is a team effort. Learn from mentors, collaborators and peers, but have the confidence to think independently. If you combine passion, curiosity, and a commitment to creating positive impact, you will not only build a successful research career but also leave a lasting contribution to science and society.

What inspired you to be in the profession you are today?

I have always had a desire to understand how things work at the most fundamental level. Research allows me to get to the bottom of important scientific problems while developing solutions that can make a meaningful impact on the world.

What is one surprising fact about your research or project that people might not know?

People may be surprised to learn that I only entered electrochemistry about a decade ago. Before that, my research focused on nanomaterial assembly and heterogeneous interfaces. Bringing a fresh perspective from materials science allowed us to rethink catalyst design and develop new interface engineering strategies for durable fuel cells.

What’s the most exciting moment you've experienced over the course of your research or project?

The most exciting moments are when companies contact us to explore collaborations. Knowing that our fundamental research has progressed to the point where industry sees a clear path toward real-world implementation is both validating and deeply motivating.
