Abstract
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 compartment including an emission source of the fuel and a first detector arranged in the compartment to detect the fuel. If the first detector detects that a concentration of the fuel in the compartment is equal to or greater than a first threshold value, a power supply to a non-explosion-proof device in the compartment is stopped.
Claims5
A fuel cell ship for propelling a hull by using electric power supplied by a fuel cell configured to generate electric power through an electrochemical reaction of fuel, the fuel cell ship comprising:
- a compartment including an emission source of the fuel;
- a first detector arranged in the compartment, the first detector configured to detect the fuel;
- a ventilation device configured to employ forced ventilation inside the compartment;
- and
- a second detector arranged around the ventilation device, the second detector configured to detect the fuel,
- wherein, based on detection by the first detector that a concentration of the fuel in the compartment is equal to or greater than a first threshold value, a power supply to a non-explosion-proof device in the compartment is configured to be stopped, and
- wherein the ventilation device is activated when the second detector is switched on.
