Abstract
A control system and method for preventing a fuel cell from overheating are disclosed. The system includes: a fuel cell that generates electric power through reaction of fuel gas and oxidation gas; a cooling line in which a cooling medium flows and performs heat exchange with the fuel cell; a cooling pump installed on the cooling line and configured to circulate the cooling medium through the cooling line; a cooling controller that controls an operating state of the cooling pump on the basis of the temperature of the fuel cell or the cooling medium; and a power generation controller that limits power generation of the fuel cell on the basis of the operating state of the cooling pump.
Claims17
A control system for preventing a fuel cell from overheating, the system comprising:
- a fuel cell configured to generate electric power through a reaction of a fuel gas and an oxidation gas;
- a cooling line through a cooling medium flows and in which the cooling medium performs heat exchange with the fuel cell;
- a cooling pump installed on the cooling line and configured to circulate the cooling medium through the cooling line when the cooling pump is driven;
- a cooling controller configured to control an operating state of the cooling pump on the basis of a temperature of the fuel cell or a temperature of the cooling medium;
- and
- a power generation controller configured to limit power generation of the fuel cell according to the operating state of the cooling pump.
A control method for preventing a fuel cell from overheating, the method comprising:
- estimating a temperature of a fuel cell or sensing a temperature of a cooling medium;
- controlling an operating state of a cooling pump that circulates the cooling medium through a cooling line connected to the fuel cell on the basis of the estimated temperature of the fuel cell or the sensed temperature of the cooling medium;
- and
- limiting power generation of the fuel cell on the basis of the operating state of the cooling pump.
