Electrochemical impedance spectroscopy is one of the important indicators for the fuel cell performance, so its accurate measurement is necessary for the fuel cell system's efficient and reliable operation. In this paper, the fuel cell EIS measurement is to modulate DC/DC ripple which is introduced into the fuel cell as excitation source. In order to meet requirements of rapidity and stability in...
The ohmic resistance of proton exchange membrance fuel cell(PEMFC) is mostly decided by PEM's water content, which can directly affect the efficiency of electricity generation, so it is very important for the measurement and control of PEMFC's humidity by means of monitoring its internal resistance. However, the internal resistance is hard to measure exactly because of its non-linear and time-varying...
