    Definition "anode or cathode layer that is added on both sides of the membrane in PEM fuel cells" Reference "Department of Energy > The Office of Energy Efficiency and Renewable Energy > Hydrogen & Fuel Cell Technologies Office > Fuel Cells > Parts of a Fuel Cell (9.4.2024)"
    Comment Conventional catalyst layers include nanometer-sized particles of platinum dispersed on a high-surface-area carbon support. This supported platinum catalyst is mixed with an ion-conducting polymer (ionomer) and sandwiched between the membrane and the GDLs. On the anode side, the platinum catalyst enables hydrogen molecules to be split into protons and electrons. On the cathode side, the platinum catalyst enables oxygen reduction by reacting with the protons generated by the anode, producing water. The ionomer mixed into the catalyst layers allows the protons to travel through these layers.
