What we do

As the expert in the implementation of the most demanding metallic bipolar plates, CellForm provides its customers around the world with cutting-edge solutions.

Our experience and know-how manifests in a history of welding bipolar plates which goes way back to the beginning of the Mercedes-Benz NECAR series in 1994. Based on more than 50 years of experience in tool development and manufacturing, our unique forming strategy allows us to implement even the most sophisticated flow field channels – putting us in a leading position within the industry regarding accuracy and filigree.

These highly advanced forming and welding techniques consequently ensure superior quality standards and new dimensions of efficiency.
Taking into account the need for large quantities of low-priced bipolar plates on the market, the design of our overall concept in combination with our standard system allows us to manufacture bipolar plates in great numbers at an industry-leading price.

We excel at pushing the limits. We are forming future efficiency.

Value Proposition

Fuel-cell systems will contribute a great deal to future technologies – in both industrial plants and novel mobility concepts.

We have devoted ourselves to supplying our customers with metallic bipolar plates with market leading properties in terms of (1) efficiency and geometrical limits and (2) geometric dimensional accuracy.
We can effectively handle sheet thicknesses in the order of 0.05 mm at a high level of accuracy, which surpasses most of the industries’ standards. By virtue of our special welding-techniques, we ensure a flawless welding quality even on exceptionally thin metal sheets.

Thanks to sophisticated automation systems, we can effortlessly handle high production volumes and are able to offer at a highly competitive price.

Filigree || Efficiency

Our unique CellForm-Strategy allows us to implement even the most sophisticated and filigree flow fields. In combination with a thickness down to 0.05mm we enable flow fields for the most efficient fuel cell systems.
Accuracy || Durability

Our tools are designed for maximum flow field accuracy. Every part is manufactured in our cutting-edge machinery in a fully air-conditioned plant. Combined with our overall forming concept this strategy allows us to reach an industry-leading level of channel accuracy for the most durable fuel cell systems in mobile applications.
Speed || Low cost

From the beginning of our research activities, there was always one important premise: cycle time.
Taking into account the price pressure of the automotive industry and the requirement for new powertrains, only a price efficient way of part- and system manufacturing will take the lead into future mobility. CellForm provides its customers with more than cutting-edge technology and freedom in flow field design. We challenge today's most detrimental aspects of fuel cell systems: efficiency and price.
"We defined an all-new way of building a forming tool.
Not only did we question every single step of setting up a tool, but we also developed a new way of technical coordination and fine-tuning."

Product Example

Application Areas

Fuel cell technology has a wide range of utilization and it is expected to play a crucial role in stationary, mobile and portable applications.

Our very thin and filigree bipolar plates enable us to achieve a significant weight reduction in fuel cell stacks and are therefore an ideal solution for all sorts of future mobility concepts.

From forklifts through cars to ships or even airplanes - CellForm will manufacture customized and low-priced solutions from small to large scale quantities.
