Abstract
Systems, methods, and devices of the various embodiments provide a hardware and software architecture enabling electrochemical impedance spectroscopy ('EIS') to be performed on multiple electrochemical devices, such as fuel cells, at the same time without human interaction with the electrochemical devices. In an embodiment, a matrix switch may connect each cell of a fuel cell stack individually to an EIS analyzer enabling EIS to be performed on any fuel cell in the fuel cell stack. In a further embodiment, the EIS analyzer may be a multi-channel EIS analyzer, and the combination of the matrix switch and multi-channel EIS analyzer may enable EIS to be performed on multiple fuel cells simultaneously.
