Abstract
An apparatus and method for controlling a fuel cell which has an anode and a cathode includes first and second circuitry which are utilized, to selectively short the anode to the cathode and further is useful in measuring the rate of voltage recovery following shorting, and which can be utilized as a predictor of appropriate fuel cell hydration and can be further utilized to adjust the operational conditions of the fuel cell.
