Abstract
A method of operating an electrochemical cell stack is provided. The method includes feeding a reactant gas to the cell stack. The flow of the reactant gas is halted to at least one cell in the cell stack. The voltage applied to the at least one cell is increased. The flow of reactant gas to the at least one cell is initiated in response to the voltage increasing above a threshold for a predetermined amount of time.
