Fuel cell systems

Fuel cells generate DC power with an inherent ground impedance that can interfere with connected electrical systems. KraftPowercon’s DCKraft™ converter disconnects this ground from the main DC switchboard, providing galvanic isolation that protects against short circuits, isolation faults, and stack-induced disturbances. This ensures safe and stable integration of fuel cell power into marine, industrial, or grid-connected systems.

Fuel cells produce fluctuating voltage and current, requiring converters that can stabilize output under partial load or transient conditions. Using Silicon Carbide (SiC) power electronics, DCKraft™ achieves >98% efficiency while maintaining clean, stable power delivery to connected loads — even under dynamic conditions. This maximizes uptime, reduces heat losses, and extends component life.

DCKraft™ offers 200 kW modules that can be stacked in rack configurations up to 800 kW per enclosure, with scalability to 10 MW for large installations. This modular approach supports industrial fuel cell plants, marine propulsion systems, and heavy-duty stationary power setups, ensuring flexible design and easy capacity expansion.

The DCKraft™ converter provides fault isolation between the fuel cell stack and the DC bus, shielding the system from electrical interference, overloads, or stack behavior irregularities. This prevents fault propagation across the network, safeguards sensitive equipment, and ensures compliance with marine and industrial safety standards.

KraftPowercon’s converters are ideal for marine propulsion, stationary backup power, industrial microgrids, and transportation electrification using fuel cell stacks. They serve as the power interface between the fuel cell and the main DC system, ensuring efficient, compliant, and scalable energy transfer across diverse high-power environments.
