Study of Control Method for Proton Exchange Membrane Fuel Cell Stacks Using Overpotential Calculated from Curve Fitting Yutaro Akimoto, Keiichi Okajima



For the stable operation of proton exchange membrane fuel cells, measurements are made using sensors, and the controls are designed to detect, identify, and avoid defects based on the measured values. In this study, the control index using overpotential was calculated by the curve-fitting method. This method can increase the in-service operation and lower the cost because the sensors and measurement system are not used. The effectiveness of the proposed method for biased data is demonstrated, and the results are described.
