What Infinity Fuel Cell & Hydrogen does

Infinity Fuel Cell & Hydrogen, Inc., founded in 2002 by William F. Smith in Windsor, Connecticut, designs, builds, tests, and delivers complete proton exchange membrane (PEM) fuel cell power systems, electrolysis systems, and regenerative fuel cell systems. Its technology is differentiated by three patented innovations: Advanced Passive Water Removal (APWR) that eliminates centrifugal water management systems, Non Flow Through (NFT) architecture achieving near 100% reactant utilization, and a four-chamber bipolar plate design enabling air-independent operation in zero-gravity, underwater, and space environments. Core products include the XPS and XPSL fuel cell stacks, HyGen high-pressure electrolyzers generating hydrogen at greater than 2,000 psi, the XStorra regenerative fuel cell system, and the Mystic 2000 AUV power system that achieved a 2,023 km fully submerged endurance run in April 2026.

The company serves four primary markets: space and aerospace (NASA Glenn Research Center and Johnson Space Center programs, Blue Origin New Shepard flights, Axiom Space lunar and LEO missions), unmanned underwater vehicles (US Navy LDUUV program targeting 70-day submerged operations, Cellula Robotics, DRDC), mobile and remote power (US Marines expeditionary microgrids via XStorra), and renewable green energy and power-to-gas applications. Revenue is generated primarily through custom development contracts and small-batch hardware sales to government and enterprise customers, with pricing on a contract basis given the mission-specific nature of systems.

Commercial channels include direct sales to NASA and defense customers, a 2025 joint venture (Nautigen) with Cellula Robotics for exclusive global marine distribution, and an OEM integration partnership with Plug Power for large-scale electrolyzer stacks. The company has raised approximately $5.7 million across two Regulation CF crowdfunding rounds, secured a $13 million minimum funding commitment from the Nautigen JV, and received over $5 million in purchase orders since the start of 2026. It holds AS9100 aerospace certification, NASA TRL 7 status, and multiple R&D 100 and NASA Group Achievement awards.

Core offering

Infinity Fuel Cell & Hydrogen designs, manufactures, and delivers complete Proton Exchange Membrane (PEM) fuel cell power systems, high-pressure electrolysis systems, and regenerative fuel cell microgrids for spacecraft, aircraft, underwater vehicles, and remote renewable energy applications. The company's core offerings are the XPS/XPSL Extreme Power System fuel cell stacks, HyGen high-pressure PEM electrolyzers generating hydrogen above 2,000 psi, and XStorra regenerative fuel cell systems that combine hydrogen generation, storage, and power for mobile/remote applications including US Marine Corps and AUV deployments.

Product overview

Infinity Fuel Cell and Hydrogen designs, manufactures, and delivers complete proton exchange membrane (PEM) fuel cell power systems, electrolysis systems, and regenerative fuel cell systems for aerospace, underwater, and renewable energy applications. The product portfolio centers on three core solution areas: Fuel Cell Power (XPS/XPSL series), Hydrogen Generation (HyGen high-pressure electrolyzers), and Regenerative Energy (XStorra systems). The XPS Extreme Power System provides scalable, air-independent fuel cell power with patented Advanced Passive Water Removal (APWR) technology, while the HyGen electrolyzer generates hydrogen at 2,000+ psi. The XStorra regenerative system combines these technologies for complete energy storage solutions. Recent additions include the Mystic 2000™ AUV Power System for underwater vehicles and large-scale systems integrating Plug Power electrolyzers for renewable microgrids. All products leverage proprietary air-independent, zero-gravity capable PEM technology initially developed for NASA space programs.
