Fuel cell ship

A power generation system that supplies a propulsion unit or onboard equipment with power from a fuel cell, the power generation system comprising:

• a fuel cell compartment in which the fuel cell is installed;
• a tank compartment in which a fuel tank that stores fuel is installed;
• a fuel supply pipe that supplies the fuel from the fuel tank to the fuel cell, wherein the fuel supply pipe includes at least two shutoff valves, a tank side shutoff valve installed in the tank compartment, and a fuel cell side shutoff valve installed in the fuel cell compartment,
• a fuel discharge pipe that branches off from the fuel supply pipe between the tank side shutoff valve and the fuel cell side shutoff valve;
• and
• a release valve installed in the fuel discharge pipe, wherein when a fuel gas detector detects that a concentration of the fuel is equal to or higher than a predetermined value, the power generation system closes the tank side shutoff valve and the fuel cell side shutoff valve, and opens the release valve.
