Abstract
A fuel cell system and a control method using the same. The fuel cell system includes a propeller wing of a flying object and connected to a rotor, a main radiator and a sub-radiator arranged so that heat of cooling water is dissipated by a downdraft generated by rotation of the propeller wing, and a controller to provide the cooling water to one or both of the main radiator and the sub-radiator based on an operation mode of the flying object.
Claims19
A fuel cell system comprising:
- a propeller wing of a flying object and connected to a rotor;
- a main radiator and a sub-radiator arranged so that heat of cooling water is dissipated by a downdraft generated by rotation of the propeller wing;
- and
- a controller configured to provide the cooling water to one or both of the main radiator and the sub-radiator based on an operation mode of the flying object.
1 more element
A method of controlling a fuel cell system, the method comprising:
- dissipating heat of cooling water through a main radiator when a flying object is initially started;
- selecting an operation mode among an emergency operation mode, a normal operation mode, and a maximum output operation mode of the flying object;
- and
- selectively dissipating the heat of the cooling water through one or both of the main radiator and a sub-radiator according to the operation mode.
1 more element
A method of controlling a fuel cell system, the method comprising:
- setting an initial number of rotations of a cooling water pump according to an operation mode of a flying object;
- determining whether a temperature of cooling water is higher than a target temperature;
- determining whether a difference between the temperature of the cooling water and the target temperature is within a preset temperature difference in a case in which the temperature of the cooling water is higher than the target temperature;
- and
- increasing the number of rotations of the cooling water pump in a case in which the difference between the temperature of the cooling water and the target temperature is greater than the preset temperature difference.
