The proton exchange membrane (PEM) is a critical element; it is made of semipermeable polymer and serves as a barrier between the cathode and anode during fuel cell construction. Additionally, membranes function as an insulator between the cathode and anode, facilitating proton exchange and inhibiting electron exchange between the electrodes.
These concepts are expected to be implemented in next-generation PEMFCs to achieve high power density. This Perspective reviews the recent technical developments in the components of the fuel cell stack in proton-exchange membrane fuel cell vehicles and outlines the road towards large-scale commercialization of such vehicles.
Moreover, proton exchange membranes are prone to dehydration in high temperature and dry environments, resulting in the reduction of the cell performance. Because of the relatively harsh operating conditions of portable applications, it is not possible to maintain the best performance of the fuel cell.
