The adhesives are expected to cure in seconds and are suitable for efficient fuel cell production.
According to Delo, hydrogen is playing an increasingly important role on the road to carbon-neutral mobility, becoming more prevalent as an alternative to battery-electric drivetrains in the transportation sector. Within hydrogen powertrains, fuel cells serve as a key technology. However, the methods currently used for fuel cell assembly are reaching their limits in large-scale production, particularly in terms of short production cycles, energy efficiency, process reliability, and design freedom.
Delo Industrial Adhesives has developed promising solutions— which we are already implementing in customer projects—for the bonding and sealing of essential areas found within the fuel cell and its functional requirements.
Delo’s adhesives are said to enable the reliable connection and sealing of bipolar plate half-shells. They also ensure the solid sealing of media circuits (hydrogen, oxygen, coolant) within the stack to one another and to the outside. The company’s adhesives are also ideal for gas diffusion layer fixation.
Delo offers a range of adhesives for bonding applications in fuel cells, tailored to requirements from production to operation. The company’s light-curing or preactivation adhesives are optimised for fast, precise, and automated production. This is claimed to ensure maximum production efficiency in large-scale production and enables short cycle times while simultaneously reducing energy consumption. Delo envisions its adhesive solutions being particularly suited for long-distance heavy-duty vehicles such as trucks, ships, trains, and airplanes.
