Abstract
Proton exchange membrane fuel cells (PEMFCs) have the perception to strongly reduce global emissions through an environmentally friendly perspective. Graphene has drawn global attention and has positioned itself as a potential material for bipolar plates application. This study reviews the application of graphene and summarizes the degradation of graphene coating that has become a significant issue in the improvement of PEMFC's performance. In the analysis, the degradation and its dissolution processes are presented. The need to improve the material selection focused mitigation on fabrication defects that act as initiation sites for graphene coating degradation is recommended. Finally, this review through recommendation endeavors to prevent graphene coating degradation and reduces high costs associated with the replacement of bipolar plates in the PEMFCs.
