"Because we have so many filigree structures in the bipolar plate, every influence from a material perspective obviously has to be taken into account. Grain size, thickness tolerance, roughness – it all plays a role."
Tobias Heinz,

CellForm Hydrogen
"As a product, the bipolar plate looks pretty trivial to many who are not familiar with it. If you try it, you quickly notice that the forming just isn't standardeven if the product looks trivial."
Simon Brugger,
Co-Founder & CEO
CellForm Hydrogen
"It is a huge advantage to be able to access the relevant equipment to produce prototypes and small series. This saves valuable time and costs which can be a critical advantage in new project acquisition."
Dr. Dominik Kraus,
Head of Stamping Technology
Freudenberg Sealing Technologies
"The seal issue has so far not been properly addressed."
Jürgen Emig,
Director Pre-Product Development Hydrogen Applications
Freudenberg Sealing Technologies
"Dispensing technology today has many advantages over other methods, but must continue to evolve."
Janik Hermann,
Product Manager Dispensing Systems
Datron
"If you are looking to operate the machines properly, over a long period of time, especially with large quantities, then cleanliness and cleaning of the system, and especially of the plates, is a very big issue."
Daniel Schönbohm,

Worthmann Maschinenbau/MACEAS
"If we were to come away from metal nitrides combined with precious metals and look more toward diamond-like carbon, and if we could also still achieve the same durability, then the costs would be halved at a stroke."
Dr. Ing. Herbert M. Gabriel,
Managing Director
PVT Plasma und Vakuum Technik
"This shows that producing bipolar plates is not straightforward."
Dr.-Ing. Jörg Karstedt,
Head of the Department Fuel Cells and Stacks
Zentrum für BrennstoffzellenTechnik
"Quality and safety come first. This does not mean that we will never talk about price, but we are not in a mass market. For aviation, I don't see the possibility of offering the highest quality with minimum costs. Not yet."
Patrick Raynal,
Project Manager
Safran
"I can't replace one production technology with another and, in doing so, maintain the same underlying parameters for the constructive design."
Dr. Stephan Kohlsmann,
Managing Director
Profiroll Technologies
"Currently, we are now aiming for a hundred plates per minute. We are therefore still some way away from the ten-hertz technology. Although that's really only part of the story; it always depends on the plate size, the thickness of the metal and the film. Ten-hertz technology is more of a buzzword for policymakers."
Dr. Michael Hirsch,
Engineer
Profiroll Technologies
"In a flow process in which all processes are arranged in a web, the slowest process obviously determines the web speed."
Werner Volk,
Business Development Manager
OPTIMA packaging group
"At some point, for bipolar plates and fuel cell stacks, there will certainly also be standards for individual parts and components. But not for the overall system or the individual design of the bipolar plate."
