Lightweight at low cost: The special shape of the patented D.bow end plate technology from Tribecraft enables evenly distributing the clamping forces of the bipolar plates of a fuel cell stack.
Reputable customers as the Paul Scherrer Institute, the ETH Zürich, Viessmann or Daimler conducted fuel cell research or predevelopment using Tribecrafts patented D.bow system.
The special shape of the D.bow end plate technology from Tribecraft enables evenly distributing the clamping forces of the bipolar plates of a cell stack. And at an absolutely minimal weight. In the past, end plates could only be manufactured with extensive milling of solid aluminum. D.bow permits producing large volumes at the lowest possible cost thanks to metal extrusion profiles and injection molded plastic parts with integrated fluid lines.
“The modifications reduced the weight of the stack fom 9 to 4 kg, while keeping the cells basically the same.”
