    Nexa Training System
    1.2 kW Fuel Cell Training System

    Brand: Heliocentris

    State-of-the-art laboratory equipment for experimental setups sporting a fully integrated industrial fuel cell module. It focuses on electrical system design and hybridization.
    The system helps learners to prepare for the practical application of fuel cell technology.

    The Nexa® Training system conveys advanced know-how in the dimensioning and hybridization of fuel cell energy systems and can also be used as a power system for research.

    Students can design and simulate fuel cell energy systems towards specific load profiles on the basis of the system’s industrial components. Fuel Cell module, hydrogen storage, battery and power electronics can be examined and influenced separately. Data acquisition and system configuration are conveniently executed via computer. Users learn about load profiles, efficiencies and design criteria, making them experts in system dimensioning.

    Researchers can use the system to examine detailed system performance and various set-ups:

    • Hybrid Electric Vehicle Power Supply
    • Uninterruptable Power Supply (UPS)
    • Autonomous Power Supply
    • Portable Power Supply

    The LabView-based software of the Nexa® Training System enables the control of the overall system as well as the supported execution of experiments.
    Data is displayed in a clear layout on system and component levels and can be modified as desired. Measurements can be recorded and exported for further processing at any time.
