REXH₂ Marine Hydrogen Power Generator

The REXH₂ from EODev is a modular "Plug & Play" hydrogen fuel cell generator for marine and river vessels. Built around Toyota's latest-generation 70 kW fuel cell, it supplies power for propulsion and/or onboard systems with no emissions and minimal noise, and works as a range extender in hybrid electric or diesel-electric installations.

Key features

• 70 kW fuel cell module with a footprint under 2 m³
• Up to 8 units can be paralleled for 560 kW
• Hybrid operation: compatible with any electrical system, ideal alongside batteries; can be combined with a diesel-electric unit for zero-emission sailing in ports, coastal and protected areas
• Cooling via seawater or the ship's closed glycol cooling circuit
• Ventilation system keeps the unit under negative pressure for operational safety
• Electrical cabinet with control system and safety card for communication with the ship's electrical interfaces
• Real-time monitoring of performance and hydrogen level, plus maintenance anticipation via EODev Connect
• Three hatches for maintenance access
• Toyota fuel cell rated for up to 13,000 hours of use
