The transition toward sustainable transportation and the growing global focus on reducing carbon dioxide emissions have accelerated the development of fuel cell vehicles (FCVs) as an alternative to conventional internal combustion engine technologies. Among the various fuel cell technologies, polymer electrolyte fuel cells have emerged as a promising solution due to their high energy efficiency and zero tailpipe emissions. To achieve widespread adoption of FCVs, manufacturers must not only improve fuel cell performance but also enhance durability, productivity, and cost-effectiveness in mass production. These requirements place significant demands on the materials used within fuel cell stacks, particularly adhesives, which play critical roles in bonding, sealing, and protecting sensitive components under challenging operating conditions involving heat, moisture, and chemical exposure. In response to these challenges, Toagosei developed specialized UV-curable and hot-melt adhesive technologies that were adopted in Toyota’s second-generation MIRAI fuel cell vehicle. This paper describes the development, performance requirements, and application of ARONIX®️ UVX and ARON MELT®️ adhesives, highlighting their contributions to the durability, manufacturability, and reliability of advanced fuel cell systems.
