Structure and method for fuel cell system where multiple fuel cells and power electronics feed loads in parallel allowing for integrated electrochemical impedance spectroscopy (EIS)
Systems, methods, and devices of the various embodiments enable electrochemical impedance spectroscopy (“EIS”) to be performed on electrochemical devices, such as fuel cell stack segments, by power electronics connecting the electrochemical devices in parallel to a common load and/or bus. In an embodiment, the power electronics may compensate for any ripple generated during EIS such that no ripple is realized at the common load and/or bus.
