ZeroAvia is scaling its SuperStack Flex fuel cell technology to be used for smaller uncrewed aircraft systems and VTOL aircraft.

ZeroAvia is making its SuperStack Flex fuel cell technology available to companies developing various uncrewed aircraft systems and VTOL aircraft. This week, the propulsion innovator reported that new additive manufacturing techniques have allowed it to scale the hardware to provide smaller versions of the equipment with lower power levels of between 100 and 600 kilowatts.

Originally, the low-temperature proton exchange membrane fuel cell stacks were developed for the ZA600 hydrogen-electric propulsion system ZeroAvia is using to convert fixed-wing regional aircraft with up to 20 seats. The company said it is in discussions with an undisclosed customer over plans to apply a scaled modular version of the hardware for an unspecified application.
