Based on a deep understanding of fuel cell system design and E/E architecture of fuel cell powertrains, we help our customers transition to zero-emission mobility and transportation.

We offer solutions ranging from innovative conceptual design studies, fuel cell system engineering, prototyping and development towards series production including the supply of range extender systems.

Our complete fuel cell range extender system solutions (e.g., 15, 30, 45 kW) based on standard modules with customization options ensure a time- and cost-efficient system development. Customers profit from the opportunity to choose our state-of-art patented technology and combine fuel cell Stacks for scale-up or down processes.

Furthermore, we offer specific modeling, simulation and software solutions for PEM fuel cell systems, developed in-house by highly experienced teams and provide support according to your project-specific needs.


STACK Hydrogen Solutions is a dynamic high-tech startup based in Aachen. As an ambitious team of fuel cell system and automotive experts, we develop innovative hydrogen solutions for commercial vehicle powertrains to shape the emission-free mobility of the future.

As an efficient problem solver for our clients, our engineering approach is innovative, pragmatic and fast. With our engineering services and hardware, we support our clients on their journey towards long-range e-mobility. Our fuel cell range extender solutions are based on proven standard modules and foster complementary strengths of battery as pure energy provider on the one hand, and fuel cells as an energy converter on the other.
