The global shift toward decarbonization has placed hydrogen at the forefront of sustainable energy solutions, driven by its ability to deliver zero-emission power when produced from renewable sources. As governments and industries grapple with ambitious climate targets, hydrogen fuel cells have emerged as a critical technology offering both electrical generation and heat recovery capabilities. Within this context, air cooled hydrogen fuel cell stacks present a compelling value proposition: by eliminating complex liquid coolant loops, they simplify balance-of-plant requirements and reduce long‐term maintenance burdens. These attributes make air cooled stacks particularly attractive for distributed applications where reliability and ease of installation are paramount.

Transitioning from early niche pilots to broader commercialization, the technology landscape for air cooled stacks has matured significantly over the past five years. Membrane electrode assemblies have seen performance enhancements that sustain power outputs under varied ambient conditions, while bipolar plate materials have evolved to balance thermal conductivity with corrosion resistance. Simultaneously, integration of digital monitoring-leveraging artificial intelligence and digital twin frameworks-has enabled real-time thermal management that optimizes stack performance and extends operational lifespans. Together, these technical and digital innovations are catalyzing the adoption of air cooled hydrogen fuel cells across material handling, remote telecommunications, and emerging mobility segments.

Breakthroughs in catalyst design and membrane chemistry are propelling air cooled hydrogen fuel cell stacks beyond traditional performance thresholds. Novel catalyst formulations employing reduced platinum loadings and alternative alloys have demonstrated sustained activity at elevated temperatures, a critical step toward lowering system costs and enhancing durability. Concurrently, advancements in high‐temperature proton exchange membranes are broadening the operational envelope to exceed 100 °C, improving tolerance to fuel impurities and facilitating combined heat and power integration, particularly in residential and light industrial settings.

The introduction of new tariff measures by the United States in 2025 is reshaping the cost and supply dynamics of air cooled hydrogen fuel cell stacks. President Trump's so‐called “Liberation Day” tariffs established a baseline duty of 10 percent on clean technology imports, with steeper rates imposed on key components like fuel cell bipolar plates and catalyst materials sourced from specific countries. This policy pivot has immediately increased the landed cost of imported stack subcomponents, prompting stack manufacturers to reevaluate sourcing strategies and buffer inventory holdings to maintain project schedules.

Building on this framework, the Foreign Pollution Fee Act of 2025 introduced differentiated tariffs on hydrogen imports and related equipment based on embedded carbon intensities. Under the new regulations, hydrogen stacks manufactured with higher upstream emission footprints face additional duties, while cleaner‐production pathways benefit from reduced rates. This mechanism is intended to incentivize low‐carbon manufacturing but also adds complexity to cross‐border supply chains and compliance processes.

As a result, key stack manufacturers are accelerating local assembly operations and forging partnerships with domestic suppliers to mitigate tariff exposure. However, upstream components such as specialized catalysts and graphite plates still attract duties on raw material inputs, limiting the extent of cost relief achievable through nearshore production. These layered tariff effects highlight the need for agile supply chain strategies that balance cost, compliance, and performance imperatives.

Disaggregating the air cooled hydrogen fuel cell stack domain by cell technology reveals distinct trajectories. Proton exchange membrane stacks dominate due to their compact footprint, low operating temperature, and rapid response to load changes, making them the primary choice for material handling vehicles and rapid‐start stationary backup power installations. Meanwhile, alkaline fuel cells retain relevance in portable power units and niche industrial applications, prized for their robust tolerance to fuel impurities and cost advantages at small scales. Phosphoric acid stacks occupy a middle ground, delivering stable performance in combined heat and power setups but with higher system complexity that confines them to larger residential and light industrial installations.

Power output segmentation further refines market understanding. Systems below five kilowatts excel in telecom backup and portable power scenarios, where minimal balance‐of‐plant requirements and low maintenance are critical for remote deployments. Midrange stacks offering five to one hundred kilowatts serve as workhorses in warehousing and grid‐tied microgrids, balancing flexibility with cost‐effectiveness. High‐power units exceeding one hundred kilowatts are increasingly deployed for bulk grid support and large facility backup, capitalizing on modular air cooled designs that scale without proportional increases in thermal management complexity.

Evaluating application and end‐user context underscores the breadth of adoption. Material handling operations are transitioning away from conventional batteries to embrace fuel cell forklifts for sustained uptime and rapid refueling cycles. Portable power markets leverage air cooled stacks for field communications and emergency response equipment, valuing their lightweight and rugged form factor. In residential settings, combined heat and power configurations deliver both electricity and domestic heating, while industrial and commercial customers utilize grid support and telecom backup installations to enhance energy security and resilience. Across these scenarios, planar stack assemblies are favored for their low profile and ease of integration, whereas tubular architectures offer robustness in high‐temperature or corrosive environments.

Regional dynamics in the Americas are shaped by expansive policy incentives and infrastructure investments. The United States, under the Inflation Reduction Act, allocated significant funding for clean hydrogen demonstration projects and tax credits for fuel cell systems, accelerating deployments in logistics hubs and critical backup power sites. Canada complements this momentum with federal grants targeting hydrogen fueling stations and remote microgrid pilots, solidifying North America’s position as a leading hub for air cooled stack innovation and early adoption.
