en.Wedoany.com Reported - Researchers at the University of New South Wales (UNSW) in Sydney, Australia, recently redesigned the hydrogen fuel cell, aiming to advance its application in fields such as aviation and heavy transport. This technology converts the chemical energy of hydrogen and oxygen into electricity, with water and heat as its primary emissions, and is considered a relatively clean power solution.

The UNSW team explains that this hydrogen fuel cell improvement scheme employs micro-scale engineering to incorporate fine channels, each about 100 micrometers wide, separated by micro-ridges of similar dimensions, into the cell's interior. This allows excess water and gas to be expelled promptly before accumulation, thereby reducing the risk of efficiency loss due to clogging.

The researchers state that the new hydrogen fuel cell design reduces reliance on expensive materials like platinum without increasing costs, and makes the entire system lighter and easier to deploy. Senior Researcher Dr. Quentin Meyer said, "Our design requires only minor structural changes to significantly improve the efficiency of the hydrogen fuel cell."

Meyer also added, "Typically, there's no way to drain the water out. But these 'lateral bypasses' act like escape routes, meaning water no longer accumulates and causes the cell to stop working. The redesigned fuel cell achieves a 75% increase in output power compared to traditional designs." Currently, the team is focusing on application scenarios like low-altitude aircraft, hoping to leverage the longer endurance advantage of hydrogen fuel cells to bring the technology closer to market adoption.
