Metallic Bipolar Plates

Vacuum Coating Equipment & Technologies

Manufacturers of bipolar plates for PEM fuel cells and electrolyzers face the dual challenge of serving a rapidly expanding market while elevating their production processes to a new level of industrialization.

We provide solutions tailored to both current and future needs—cost‑efficient, highly productive, and designed for seamless scaling. Our coating platforms support the entire journey, from research and development to full‑scale mass production.

Advantages of bipolar plate coating

Bipolar plates must be durable, conductive, and cost‑effective. To achieve this, metallic plates are coated with functional layers, typically applied using PVD technologies.

For PEM fuel cells, we have gone a step further by developing and validating our own carbon‑based layer stacks. These coatings are engineered to meet the demanding performance requirements of bipolar plates in a scalable and industrially robust way.

From early‑stage development to the implementation of a fully industrialized coating solution, we support you throughout the entire process.
