Abstract

A strategy of controlling a state of hydration of a fuel cell(s) and actively managing operation of the fuel cell(s) to achieve a desired state of hydration. The control strategy monitors the state of hydration and a rate of change of the state of hydration which are used to control the operation of the fuel cell(s). A supervisory control strategy is implemented that alters the operating parameters of the fuel cell(s) based upon the state of hydration, the rate of change of the state of hydration, and a desired operational range for the state of hydration.
