British Scientists Achieve Major Breakthrough in Fuel Cell Recycling
United Kingdom, Saturday, 10 May 2025.
A new ultrasonic technique allows rapid recycling of hydrogen fuel cells, overcoming challenges of harmful chemicals, and paving the way for sustainable energy solutions.
Revolutionary Sound-Based Recycling Process
Researchers at the University of Leicester have developed a groundbreaking method that employs ultrasonic sound waves to separate valuable materials from used hydrogen fuel cells [1][2]. The innovative process creates microscopic bubbles in a liquid medium that, when they collapse, generate sufficient force to separate different material layers within seconds at room temperature [1]. This advancement is particularly significant as it addresses the challenging task of separating precious platinum group metals from PFAS (per- and polyfluoroalkyl substances) membranes, commonly known as ‘forever chemicals’ [3].
Industry Collaboration and Commercial Viability
The research team, working in collaboration with sustainable technology leader Johnson Matthey, has demonstrated the technique’s practical applications beyond laboratory conditions [1][7]. Dr. Jake Yang from the University of Leicester School of Chemistry emphasizes that this method revolutionizes fuel cell recycling by enabling the separation of PFAS membranes from precious metals without using harsh chemicals [3]. Ross Gordon, Principal Research Scientist at Johnson Matthey, has characterized the development as a ‘game-changer’ in fuel cell recycling approaches [8].
Environmental and Economic Impact
The technology addresses two critical environmental challenges: the recovery of valuable platinum group metals and the containment of harmful PFAS chemicals that could potentially contaminate drinking water supplies [3]. The process represents a significant advance in creating a circular economy for these essential materials, potentially reducing the cost barrier associated with platinum group metals in fuel cell technology [8]. The research has been formally documented in the scientific journal RSC Sustainability, validating its technical merit and potential industry applications [1].
