Title:
METHOD FOR CONTROLLING FUEL CELL HUMIDIFICATION AND FUEL CELL SYSTEM
Document Type and Number:
Japanese Patent JP2015043313
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To quickly and successfully control a humidification state of a fuel cell.SOLUTION: A method for controlling humidification of a fuel cell 14 comprises the steps of: measuring an impedance of the fuel cell 14 (measuring step); and adjusting an amount of humidification of the fuel cell 14 on the basis of an imaginary axis value Xi and a real axis value Xr on a complex plane of the measured impedance after the measuring step (adjusting step). The measuring step can easily measure the impedance on the basis of supply of AC current composed of one frequency of not more than 10 Hz during power generation of the fuel cell 14, thereby enabling quick and successful control of the humidification state of the fuel cell.
