Abstract
A fuel cell first and second electrode catalyst layers and a polymer electrolyte membrane (PEM) situated therebetween. A graphene-based material coated onto a first and/or second surface of the first and/or second electrode catalyst layers. The graphene-based material has a number of defects including a number of quad-vacancy (QV) defects formed by a vacancy of four adjacent carbon atoms in the graphene-based material. The number of QV defects are configured to mitigate dissolution of the first and/or second catalyst materials through the first and/or second surface of the first and/or second electrode catalyst layers.
