Heavy-Duty Vehicles (HDV) powered by hydrogen-based Proton Exchange Membrane (PEM) fuel cells offer a cleaner alternative to the diesel-powered internal combustions engine vehicles for decarbonization of long-haul transportation sectors. The development path of sub-components for HDV fuel cell applications is guided by the Total Cost of Ownership (TCO) analysis of the truck. TCO analysis suggests that the cost of the hydrogen fuel consumed over the lifetime of the HDV is more dominant due to the operation of the trucks for longer mileage (~a million miles) than the fuel cell stack Capital Expense (CapEx). Commercial HDV applications consume more H2 fuel and demand higher durability and hence the TCO of the vehicle is largely related to the fuel cell efficiency and durability of catalysts. This article is written to bridge the gap between the industrial requirements and academic activity for advanced cathode catalysts with an emphasis on durability. From a materials perspective, the underlying nature of the carbon support, Pt-alloy crystal structure, stability of the alloying element, cathode ionomer volume fraction, and catalyst-ionomer interface play a critical role in improving performance and durability. We provide our perspective on four major approaches, namely, mesoporous carbon supports, ordered PtCo intermetallic alloys, thrifting ionomer volume fraction, and shell-protection strategies that are currently being pursued. While each approach has its merits and demerits, their key developmental needs for the future are highlighted.

Electrochemical impedance spectroscopy (EIS) offers rich insights into the physical processes within batteries—but how can these measurements directly inform physics-based models? Recent work presented in this webinar demonstrates how impedance data can be used to extract grouped parameters for physics-based models such as the Doyle-Fuller-Newman (DFN) model or the reduced-order single particle model with electrolyte (SPMe).
