Proton exchange membranes currently have a growing demand for electric vehicle (EV) for their renewability and efficiency compared to battery powered EVs. This review explores recent advancements in the microstructural modifications of PEMFC components (anode cathode and proton exchange membrane) focusing on doping alloying and composite materials. A total of 220 research papers published over the past two decades were reviewed focusing on structural modifications that enhance catalytic performance anti-poisoning properties electrode stability and proton conductivity as well as high-temperature stability of the proton exchange membrane (PEM). Recent studies suggest that transition metals with their oxides combined with microstructural modifications can rival commercial Pt in terms of stability catalytic activity and importantly cost. Moreover carbon nanotubes (CNTs) carbon nanofibers (CNFs) and graphene offer higher surface area for catalyst to disperse. Additionally various approach have been studied to improve PEM such as doping with phosphoric acid composite membranes and 3D electrolyte structure. By utilizing these membrane electrode assembly (MEA) leads to a more reliable PEMFCs with better longetivity. The adoption of structurally enhanced non-platinum group metal or hybrid catalyst followed by a simple and scalable manufacturing technique were emphasized to reduce the production costs.
