Enabling green H2 through PEM, AEM, AEL, SOEC & PCCEL: The key to industrial decarbonisation

Whether for sector coupling, as the backbone of the hydrogen economy, or for green basic chemicals: electrolysis is the technological enabler of a climate‑neutral future. It converts electricity into molecular energy carriers, thereby opening up new degrees of freedom for energy systems, industry, and infrastructure.

FEV e+r supports a technology‑open approach with deep system understanding – from the electrochemical active area to plant integration at the gigawatt scale. We combine physics with practical application and develop solutions that are scalable, realistic, and future‑proof.

Cells

We develop, simulate, and test electrochemical cells – from material concepts and current density distribution to degradation in virtual models and long‑term testing.

Stack

From single‑cell design to multi‑cell stacks, we optimize structure, media flow, and thermal balance for maximum efficiency and service life.

System

We integrate electrolyzer stacks into complete systems – including thermal management, safety, control systems, and grid interfaces. In doing so, we optimize balance‑of‑plant components and integrate electrolyzers into higher‑level hydrogen ecosystems.

360° Electrolysis-solutions: Holistically conceived, precisely implemented

With our modular 360° approach, we support you throughout the entire development process – from initial prototypes to series production. In doing so, we combine deep engineering expertise with systems thinking and hands‑on consulting – scalable, technology‑open, and tailored to your specific requirements.

Our goal: to bring technologies to market maturity – proven, efficient, and future‑proof.
