HyPoint and Piasecki reach $6.5M deal to develop hydrogen fuel cells systems for eVTOLs
https://techcrunch.com/2021/08/24/hypoint-and-piasecki-reach-6-5m-deal-to-develop-hydrogen-fuel-cells-systems-for-evtols/

"air-cooled hydrogen fuel cell systems that it says have triple the power-to-weight ratio of traditional liquid-cooled hydrogen fuel cells. Now, the fuel cell developer is adding Piasecki Aircraft Corporation to its list of partners... goal is to create a system that has four times the energy density of existing lithium-ion batteries, double the specific power of existing hydrogen fuel cell systems, and that costs up to 50% less relative to the operative costs of turbine-powered rotorcraft"
