Title:
FUEL CELL SYSTEM AND METHOD FOR MEASURING AC IMPEDANCE
Document Type and Number:
WIPO Patent Application WO/2007/004732
Kind Code:
A1
Abstract:
Disclosed is a fuel cell system wherein an ac impedance can be measured. The fuel
cell system comprises a power generation stabilizing means (103) for stabilizing
power generation of a fuel cell (100), and an impedance measuring means (104)
for measuring an ac impedance after power generation of the fuel cell (100) is
stabilized. Since the ac impedance in a low frequency range is measured after
power generation of the fuel cell (100) is stabilized, no external disturbance
occurs during measurement and thus the ac impedance can be measured with high
accuracy. Namely, there are disclosed a fuel cell system wherein an ac impedance
can be measured with high accuracy, and a method for measuring an ac impedance.
