ZeroAvia will work closely with supplier PowerCell Group to develop its next generation of fuel cell technologies suitable for hydrogen aviation.
Under a Memorandum of Understanding (MOU), ZeroAvia will support the Swedish manufacturer in developing higher-temperature fuel cells. This can allow for a reduction in cooling and humification, “simplifying the architecture and improving the amount of power for a given unit of weight.”
Currently, ZeroAvia is designing a multi-stack balance-of-plant system using PowerCell’s low-temperature PEM stacks applicable to aviation, making them a key supplier to the first 600kW powertrain (ZA600) for 20-seat aircraft.
ZeroAvia’s high-temperature PEM (HT-PEM) fuel cell stacks are expected to help deliver a ZA2000 powertrain for 40-80-seat aircraft. H2 View understands ZeroAvia has already demonstrated an “industry record power density” of over 2.5kW/kg at the cell level, with plans to reach 3+kW/kg in the coming months.
