MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641020780 A) filed by Saveetha Engineering College, Chennai, Tamil Nadu, on Feb. 23, for 'graphene-enhanced electrodes for high-output fuel cell applications.'
Inventor(s) include Joyal Isac Sankar; and Dr. Vinothkumar Panjanathan.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "This invention presents a graphene-enhanced electrode design for high-output fuel cell applications, aimed at significantly improving power density and overall energy efficiency. The electrodes incorporate multi-layer graphene sheets integrated with platinum nanoparticles, achieving a surface area of -2500 mVg and enhanced electron conductivity of 1.2 x I O'* S/m. Electrochemical testing demonstrates a 35% increase in current density compared to conventional carbon-based electrodes, reaching l.SA/cm^ at 0.6V in proton exchange membrane fuel cells (PEMFCs). Oxygen reduction reaction (ORR) kinetics are accelerated, with a Tafel slope reduction from 72 mV/dec to 48 mV/dec, indicating faster charge transfer. Durability assessments reveal stable performance over 500 hours of continuous operation, with less than 5% degradation in catalytic activity. The graphene network improves mass transport and reduces ohmic losses, enhancing thermal management and water control, offering a scalable, cost-effective solution foi advanced fuel cells in automotive, aerospace, and stationary applications."
