Proton exchange membrane (PEM) fuel cells with fluorine-free polymer membranes represent a new generation of sustainable energy converters. Traditional PEM fuel cells rely on perfluorinated membranes such as Nafion®, which offer excellent proton conductivity but raise environmental and cost concerns. Fluorine-free alternatives based on hydrocarbon polymers aim to match the performance of conventional membranes while reducing environmental impact and material costs.
At EES, we focus on integrating and optimizing materials and components to enhance the efficiency and durability of fluorine-free PEM fuel cells – especially under dry operating conditions. With 11 test benches ranging from 4 cm² single cells to short stacks, we combine advanced testing and characterization techniques to drive the next generation of fuel cell technology.
