An interdisciplinary team of researchers from the University of New South Wales, led by Dr. Quentin Meyer and Professor Chuan Zhao, has achieved a technological breakthrough that could significantly accelerate the transition to clean energy.
The researchers reengineered the architecture of hydrogen fuel cells, eliminating a key issue—water accumulation, which previously hindered oxygen flow and reduced system efficiency.
Traditionally, removing the reaction byproduct—water—required complex and energy-intensive solutions that increased the weight and cost of the systems. Australian scientists applied high-precision microengineering approaches by integrating microchannels 100 micrometers (0.1 mm) wide into the cell structure, separated by ribs of the same size. These “bypass channels” enable efficient removal of excess water and gases, preventing their buildup inside.
The results, published in the journal Applied Catalysis B: Environment and Energy, demonstrate a significant improvement: the upgraded fuel cell delivers 75% more power compared to conventional designs. At the same time, the structure has become lighter and more cost-effective, as it relies less on expensive platinum and no longer requires additional pumps or separators.
According to the authors, this technology opens up prospects for implementing hydrogen energy in sectors where battery systems are inefficient due to their weight. The primary focus is on aviation, particularly low-altitude aircraft, as well as heavy-duty transport.
The development has already been patented, and the team is currently working on scaling the technology for industrial production, bringing the era of affordable and completely clean energy closer.
