Fuel cell modules
Ready-to-connect fuel cell modules for flexible power classes
VINUITY® fuel cell modules are based on our proprietary stack platforms and cover a wide power range from 5 to 250 kilowatts. Each module is equipped with all essential components required for system integration, including air supply, DC/DC converters, and thermal management. For operation, only three external connections are required: air, hydrogen, and cooling.
The modules can be deployed individually or combined in multi-module configurations, creating scalable system solutions for mobile and stationary applications with varying power demands.
With the aim of reducing technical complexity, simplifying integration processes, and sustainably increasing operational reliability, VINUITY® continuously advances the development of its modules.
Features
- Power range from 5 kW to 250 kW
- Operating temperature from -30 °C to 55 °C
- Service life up to 30,000 hours
- Compact system and high system efficiency
- Protected according to IP67 and SAEJ2380
- Supplied with (integrated) air compressor and DCDC*
- Highly efficient hydrogen recirculation and advanced humidification

Application scenarios
Our modules are used wherever an emission-free, grid-independent, and scalable energy supply is required. They can be flexibly integrated into mobile applications such as buses, trucks, and forklifts, or operated as a stationary solution in a network, for example in data centers or industrial energy infrastructures.
Data centers
Emergency power supply for data centers is an increasing challenge, especially in urban areas, due to increasingly stringent regulations regarding gaseous, particle and noise emissions.
