Brazilian researchers investigating novel composite membranes for direct ethanol fuel cells

In Brazil, researchers from the Brazilian research institute IPEN are investigating novel composite membranes for direct ethanol fuel cells. A promising solution is tailoring new polymer-based composite electrolyte materials to replace the state-of-the-art polymer electrolyte such as Nafion. The team uses a melt extrusion process to produce composite membranes based on Nafion with additional titanate nanoparticles, which have been functionalized with sulfonic acid groups.
