Polymer electrolyte membrane fuel cell for medium- and heavy-duty vehicles: An opportunity for commercialization

Over the past few years, there has been a significant change in the global emphasis on environmentally friendly energy options, especially within the automotive sector. As a result, Proton Exchange Membrane Fuel Cells (PEMFC) have emerged as a promising technology for medium and heavy-duty vehicles (M−HDVs), offering a cleaner and more efficient alternative to conventional internal combustion engines (ICE). This attempt at intermediate commercialization leverages HDVs as a stepping stone for wider fuel cell adoption, capitalizing on the gap in electrifying HDVs. This overview will investigate the drivers behind the growing interest in PEMFC for HDV, including environmental concerns, performance advantages, and economic incentives. Moreover, key obstacles to the rapid commercialization of fuel cell technology for HDVs are evaluated, with emphasis placed on material advancements and system strategies best aligned with industry needs.
