Breakthrough Graphene Technology Revolutionizes Hydrogen Fuel Cells and Computing

Scientists from Khalifa University and the University of Manchester have developed a groundbreaking graphene device that can transform hydrogen fuel cells, computing, and catalysis. The research highlights the potential of graphene's properties, fine-tuned via electric fields, to independently regulate proton and electron currents.

Abu Dhabi [UAE], July 24 (ANI/WAM): Researchers from Khalifa University's Research & Innovation Centre for Graphene and 2D Materials (RIC2D) and the Research Innovation Centre on CO2 and Hydrogen (RICH) have teamed up with scientists from the University of Manchester to create a graphene-based device aimed at revolutionizing next-generation technologies in hydrogen fuel cells, computing, and catalysis.

Their findings, published in the esteemed scientific journal Nature, demonstrate that a graphene sheet's properties can be precisely tuned with electric fields to independently host proton and electron currents. This groundbreaking discovery lays the groundwork for a device capable of performing both computer memory and logic functions.

Dr Ahmed Al Durra, Senior Vice-President of Research and Development at Khalifa University, emphasized the significance of this multidisciplinary collaboration. 'Featured in Nature, this research highlights pivotal advancements in graphene's applications,' he said.

Collaborative efforts between RICH, RIC2D, and leading international universities underscore the robust potential of global partnerships. Dr Marcelo Lozada-Hidalgo from the University of Manchester expressed hope that these findings will inspire diverse scientific communities. Dr Lourdes Vega and Dr Daniel Bahamon Garcia from Khalifa University led the project, collaborating with experts from esteemed institutions worldwide.

By using a method known as double gating, researchers managed to independently control proton transport and hydrogenation in graphene. This technique enabled them to enhance proton flow through the material and induce states of high electrical resistance to create multifunctional devices.

The research emphasizes profound implications for proton-conducting membranes and sustainable technologies. Dr Vega highlighted the robust, reproducible control over conductive states, asserting that the discovery could unify memory and logic functions into a single device, significantly advancing various electronic applications.

RIC2D and RICH continue to spearhead innovations in graphene and 2D materials, with RICH being the UAE's only dedicated center focused on carbon capture, hydrogen, and sustainable fuels.
