An exemplary fuel cell ship is a fuel cell ship for propelling a hull by using electric power supplied by a fuel cell that generates electric power through an electrochemical reaction of fuel, and includes at least one compartment including an emission source of the fuel, and a vent pipe through which the fuel in the compartment is released to outside of the hull. A release port of the vent pipe is located at a position higher than a cabin or a bridge provided on the hull.

An exemplary fuel cell ship is a fuel cell ship for propelling a hull by using electric power supplied from a fuel cell that generates electric power through an electrochemical reaction of fuel, and includes a plurality of compartments including an emission source of the fuel, in which the plurality of compartments include a tank compartment installed therein with a fuel tank that stores the fuel and a fuel cell compartment installed therein with the fuel cell. The tank compartment and the fuel cell compartment are each sealed except for a ventilation port through which the inside of the compartment is ventilated.

To provide an air-cooled fuel cell system configured to efficiently warm up a fuel cell. An air-cooled fuel cell system, wherein the air-cooled fuel cell system comprises: a fuel cell, a reaction air supplier configured to supply reaction air to a reaction air inlet of the fuel cell, a reaction air supply flow path configured to connect the reaction air supplier and the reaction air inlet of the fuel cell, a reaction air discharge flow path configured to connect a reaction air outlet of the fuel cell and the outside of the air-cooled fuel cell system, a housing, a temperature acquirer configured to acquire a temperature of inside air discharged from a cooling air outlet, and a controller; and wherein, based on the temperature measured by the temperature acquirer, the controller controls opening and closing of the opening and closing unit and an opening degree thereof.

A fuel cell structure includes; a cell stack in which a plurality of cells is stacked; a fastening mechanism configured to fasten the cell stack in a compressed state from both sides in a stacking direction of the plurality of cells; and a load receiving mechanism configured to receive a linear expansion load from the cell stack in a compression release direction. The linear expansion load is caused by a decrease in compressive load by the fastening mechanism when a temperature of the cell stack is raised.
