In recent years, proton exchange membrane (PEM) fuel cells have regained worldwide attention from academia, industries, investors, and governments. The prospect of PEM fuel cells has turned into reality, with fuel cell vehicles successfully launched in the market.
The research on proton exchange membrane fuel cells (PEMFCs) has significantly escalated due to their exceptional efficiency and eco-friendliness, but there is still much ground to cover. These cells find applications in various sectors such as transportation, portable power, stationary power, aerospace, and underwater.
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.
A proton-exchange membrane, or polymer-electrolyte membrane (PEM), is a semipermeable membrane generally made from ionomers and designed to conduct protons while acting as an electronic insulator and reactant barrier, e.g. to oxygen and hydrogen gas.
Early proton-exchange membrane technology was developed in the early 1960s by Leonard Niedrach and Thomas Grubb, chemists working for the General Electric Company. Significant government resources were devoted to the study and development of these membranes for use in NASA's Project Gemini spaceflight program.
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.
