Fast, reliable, and scalable — DELO and DATRON present a joint system solution that revolutionizes fuel cell sealing. Discover how the partnership accelerates production and supports the transition from pilot projects to mass manufacturing.
Fuel cell manufacturers face a key challenge:
Sealing individual cells is a slow, energy-intensive process that directly affects the stack’s lifetime and reliability.
Traditional methods involve long curing times and complex workflows, making them unsuitable for industrial-scale production.
DELO and DATRON have joined forces to solve this challenge with a fully automated, high-speed sealing system.
By combining DELO’s fast-curing liquid sealant and UV technology with DATRON’s high-precision dosing system, the companies deliver speed, reliability, and production readiness. Early trials show impressive results.
DELO’s Approach and the Technical Concept
At the heart of this innovation lies DELO PHOTOBOND SL sealant, specially developed for fuel cell applications.
Applied directly as a liquid gasket, it cures within seconds under UV light.
The process is enabled by the DATRON evo 600 system, capable of dispensing at up to 50 meters per minute.
Its volumetric dosing control ensures a consistent bead profile – even at start and stop points.
Two smart features ensure seamless inline quality assurance:
Together, these elements create hundreds of precisely sealed fuel cells, ready to be assembled into a high-performance stack.
Watch the video to learn how the new manufacturing process makes an important contribution to the upcoming industrialization of fuel cell technology.
While conventional sealing processes remain slow, labor-intensive, and energy-demanding, the DELO-DATRON process proves to be a scalable, future-ready alternative, suitable for the transition from pilot to mass production.
With this new system solution, DELO and DATRON streamline fuel cell manufacturing, ensuring shorter cycle times, higher throughput, and greater reliability.
This is a significant milestone on the road toward the industrialization of hydrogen and fuel cell technology – made in Germany.
