ZeroAvia has entered into a collaboration with PowerCell Group to advance its fuel cell technologies for hydrogen aviation. The partnership, documented under a Memorandum of Understanding, will focus on developing higher-temperature fuel cells with the aim of simplifying the architecture and enhancing power-to-weight efficiency. ZeroAvia is currently working on a multi-stack balance-of-plant system utilizing PowerCell's low-temperature PEM stacks for a 600kW powertrain designated ZA600 for 20-seat aircraft. Additionally, ZeroAvia is exploring the use of high-temperature PEM fuel cell stacks from PowerCell to create a ZA2000 powertrain catering to 40-80-seat aircraft, with a focus on high power density. Val Miftakhov, ZeroAvia's Founder and CEO, expressed optimism that this partnership will drive industry transformation. PowerCell's CEO, Richard Berkling, highlighted the potential for commercial hydrogen-electric aircraft in the near future and emphasized the environmental and economic advantages for airlines and passengers. The article also mentions Scotland's Ecojet's commitment to integrating ZeroAvia's hydrogen-electric engines into its fleet, indicating a growing adoption of sustainable aviation solutions in the industry.
