Fuel cell stacks

Standardized stacks for customized integration solutions

VINUITY® fuel cell stacks are at the core of efficient, emission-free power generation from hydrogen. Our portfolio includes variants with graphitic and metallic bipolar plates that are optimized for power density, durability, or integration depending on the application.

Thanks to our flexible platform architecture, cell count, voltage levels, and operating parameters can be precisely tailored to a wide range of system requirements. This is true regardless of whether the stacks are used as standalone components in customer solutions or as the core of our own modules. The result is scalable stack solutions that can be efficiently integrated into mobile and stationary systems.

All products are based on experience from more than 600 real-world applications worldwide, are continuously being further developed, and are designed for long-term performance and cost efficiency. This results in powerful, scalable stack solutions that combine technical flexibility with economic series production capability.

Metallic fuel cell stack

Proton exchange membrane fuel cells with metallic bipolar plates offer a compact and robust solution for efficient power generation. This design enables uniform distribution of hydrogen and air as well as effective dissipation of generated heat. Due to their high power density, metallic stacks are particularly well suited for applications with limited installation space and high energy demand.

Specifications at a glance

	Series product	Next generation
Rated power (max)	120 up to 130 kW	≥ 300 kW
Volumetric power density (excl. endplates)	5.4 kW/l	≥ 6 kW/l
Gravimetric power density (incl. endplates)	> 2.6 kW/kg	≥ 3.5 kW/kg

* All specifications and data are subject to change without notice as an integral part of continuous improvements to design, function, reliability, and customer satisfaction.

For applications with high power densities and limited installation space, VINUITY® is developing the next generation of metal stacks with optimized cell geometry and improved heat dissipation. The aim is to further reduce weight, volume, and manufacturing costs while maintaining reliability and integration into standardized system environments.
