Abstract
There is provided a cooling system for a fuel cell watercraft without the necessity of a seawater pipe or a seawater pump. The fuel cell watercraft includes: an electric motor serving as a power source to generate propulsive force for a hull; a fuel cell module for generating electric power to be supplied to the electric motor; and a cooling system for cooling the fuel cell module. The cooling system includes a cooling chamber with an intake port and a discharge port that penetrate a bottom portion of the hull, a heat exchanger arranged so as to be immersed in water that is taken into the cooling chamber, and a circulation line and a pump for circulation of coolant between the heat exchanger and the fuel cell module.
