APPARATUS AND METHOD FOR CONTROLLING COOLING PUMP OF FUEL CELL SYSTEM

摘要

A method and apparatus for controlling a cooling pump of a fuel cell system are provided that improve efficiency of the fuel cell system by variably adjusting idle RPM of a pump that cools down stacks within the fuel cell system, based on temperature and flowrate of coolant The apparatus includes a storage that is configured to store a table in which revolutions per minute (RPM) of the cooling pump corresponding to temperature are recorded and a temperature measurer that is configured to measure temperature of a coolant of fuel cell stacks. In addition, a controller operates a pump driver based on the stored table to adjust the RPM of the cooling pump to correspond to the measured temperature of the coolant

1. An apparatus for controlling a cooling pump of a fuel cell system, comprising:
a storage configured to store a table in which revolutions per minute (RPM) of the cooling pump corresponding to temperature are recorded; a temperature measurer configured to measure temperature of a coolant of fuel cell stacks; and a controller configured to operate a pump driver based on the stored table to adjust the RPM of the cooling pump to correspond to the temperature of the coolant as measured by the temperature measurer.
