ZeroAvia has signed a Memorandum of Understanding with PowerCell Group to collaborate on developing next-generation fuel cell technologies for aerospace applications. Their joint research and development will focus on intermediate and high-temperature fuel cells, enabling energy-intensive uses like large fixed-wing aircraft and rotorcraft. PowerCell's fuel cell stacks have already been part of ZeroAvia's prototype powertrains for fuel cell flight demonstrators. ZeroAvia is working on a multi-stack balance-of-plant architecture utilizing PowerCell's LT-PEM stacks for its ZA600 powertrain, designed for up to 20 seat aircraft. Additionally, ZeroAvia's high-temperature PEM fuel cell stacks are crucial for the ZA2000 powertrain for 40-80 seat aircraft, showcasing record power density levels. By increasing the operating temperature of fuel cell systems, the need for cooling and humidification can be reduced, simplifying the system architecture while enhancing power efficiency. This collaboration leverages PowerCell's expertise in hydrogen-electric technologies to advance fuel cell solutions to high Technology Readiness Levels (TRL). It also allows ZeroAvia to expand its technology applications beyond aerospace while maintaining its primary focus on aviation innovation.
