How do fuel cells work on a ship?

A fuel cell stack will not operate stand-alone, but needs to be integrated into a fuel cell system to generate power. On a ship, this is called marinisation.


In the fuel cell system, different auxiliary components such as compressors, pumps, sensors, valves, electrical components and control unit provide the fuel cell stack with a necessary supply of hydrogen, air and coolant.


The control unit enables safe and reliable operation of the complete fuel cell system.


Operation of the fuel cell system in the targeted application will require additional peripheral components i.e. power electronics, inverters, batteries, fuel tanks, radiators, ventilation and cabinet.
