Abstract
A method for maintaining a target electrochemical impedance (ECI) for a fuel cell, which corresponds to a target hydration state for the fuel cell. The method includes determining a target electrochemical impedance (ECI) for the fuel cell based on current operating conditions. The method further includes determining actual ECI for the fuel cell and comparing actual ECI to the target ECI. The method further includes adjusting a cathode flow to the fuel cell based on a deviation of the actual ECI from the target ECI.
