ZeroAvia and PowerCell Group have entered into a Memorandum of Understanding (MoU) to advance next-generation fuel cell technologies in aviation. Their collaboration will focus on intermediate and high-temperature fuel cells, expanding applications to larger fixed-wing aircraft and rotorcraft. PowerCell's fuel cell stacks have been integral to ZeroAvia's prototype powertrains, with a history of successful collaboration. ZeroAvia is developing a bespoke multi-stack balance-of-plant architecture using PowerCell's low-temperature proton exchange membrane (LT-PEM) stacks. They are also working towards high-temperature PEM fuel cell stacks for larger aircraft, with industry-leading power densities. By operating fuel cells at higher temperatures, the technology simplifies architecture, enhances power output, and is suitable for larger aircraft. The partnership aims to industrialize hydrogen-electric technologies and achieve high Technology Readiness Levels (TRLs). This collaboration is seen as a step towards commercial H2-electric flights, with both companies emphasizing environmental and cost advantages. ZeroAvia's Founder-CEO and PowerCell Group's CEO expressed optimism about the future of hydrogen fuel cell technologies in aviation and beyond.
