Abstract
A method for determining when to operate a voltage recovery process for recovering a reversible voltage loss of a fuel cell stack in a fuel cell system. The method includes estimating an irreversible voltage loss of the fuel cell and an actual voltage of the fuel cell stack, and determining whether a difference between the estimated irreversible voltage loss and the estimated actual voltage exceed a threshold, and if so, the voltage recovery process is performed.
