Membrane Materials for PEM Fuel Cells in the Post-PFAS World
Membrane materials are of fundamental importance for fuel cells, even giving their name to the specific type of fuel cell, as is the case for Proton Exchange Membrane (PEM) fuel cells. Typically, these membranes consist of ionomers containing perfluoroalkyl substances (PFAS), which in turn are subject to increasing concern and proposed regulations. In response to this, alternative materials for membranes are beginning to emerge.
