Fuel Cells: Clean, hydrogen‑based power generation

Breadcrumb navigation

h2 to powerA key building block of resilient energy infrastructure

For more than 25 years, FEV has been developing fuel cell solutions and understands both the technical challenges and the practical ways to solve them reliably.
In stationary applications in particular, fuel cells are becoming a critical element of future energy infrastructure. They enable highly efficient, flexible and locally low‑emission power and heat generation, providing security of supply where resilience, decarbonization and system stability are required at the same time.

Fuel cell and stack development

FEV energy + resources offers comprehensive expertise in the development of fuel cell stacks — the core element of every fuel cell system. We support our clients throughout concept development, design and optimization to achieve high efficiency, long lifetime and cost‑effective solutions that perform not only technically, but also commercially.
Beyond individual stack development, FEV also delivers complete fuel cell system development. We design application‑specific system architectures tailored to the respective use case. The result is innovative, sustainable and economically viable fuel cell systems that meet real project requirements.

From single cell testing up to MW system tests.

Comprehensive testing is a critical step in fuel cell development to ensure performance, reliability and safety. FEV Energy & Resources operates state‑of‑the‑art test facilities and methodologies to validate fuel cell stacks and systems under realistic operating conditions.
We complement physical testing with detailed virtual models, enabling shorter development cycles, early issue detection and reduced risk during scale‑up and operation.
