PolymPart: Protons (subatomic particles) can be transferred from the anode to the cathode through the ionomer membrane in polymer electrolyte fuel cells (PEFC). Scientists can extend proton pathways by impregnating the ionomer (type of polymer) into the electrodes to achieve improved proton transfer efficiency. Since the impregnated ionomer can mechanically bind catalysts within the electrode, […]

In polymer electrolyte fuel cells (PEFCs), protons from the anode are transferred to the cathode through the ionomer membrane. By impregnating the ionomer into the electrodes, proton pathways are extended and high proton transfer efficiency can be achieved. Because the impregnated ionomer mechanically binds the catalysts within the electrode, the ionomer is also called a […]
