UNSW hydrogen breakthrough boosts clean transport prospects
27th May 2026
Researchers from the University of New South Wales (UNSW) have unveiled a redesigned hydrogen fuel cell they say could significantly improve the viability of clean-energy transport technologies for aviation, freight and other heavy industries.
The breakthrough centres on solving one of hydrogen fuel cells’ most persistent technical problems – water accumulation inside the cell, which can block oxygen flow and reduce performance. Traditional solutions often require heavy and expensive support systems, limiting the technology’s commercial appeal.
The UNSW team, led by Dr Quentin Meyer and Professor Chuan Zhao from the university’s School of Chemistry, developed a new internal architecture that allows excess water and gas to escape more effectively without adding significant cost or complexity.
According to the researchers, the redesign incorporates microscopic channels within the fuel cell structure, measuring around 100 micrometres wide. These “lateral bypasses” create escape routes for trapped water, helping maintain oxygen flow and improving overall efficiency.
Dr Meyer said the new approach delivered substantial performance improvements.
“The redesigned fuel cell achieves 75 per cent more power than traditional designs,” he said.
The research team combined advanced imaging, fluid flow simulations and precision micro-engineering to refine the design, with support from experts across several UNSW engineering disciplines.
Professor Zhao said the breakthrough could help accelerate the adoption of hydrogen technology across multiple industries.
“This breakthrough could be used in a range of different settings and brings cheap, clean, and abundant hydrogen energy to within our reach,” he said.
The team believes the technology could be especially valuable in sectors where battery-electric systems face weight and range limitations, including aviation and long-haul freight transport. The lighter design also reduces reliance on costly materials such as platinum, potentially lowering production costs.
Dr Meyer said hydrogen-powered aircraft could become commercially viable sooner than many expect, particularly for low-altitude aviation applications where fuel cells can already outperform battery alternatives in flight duration.
The lateral bypass technology has now been patented, with the UNSW researchers working towards scaling the system for broader commercial deployment.
