Abstract
A fuel cell system includes a fuel cell stack and a flow control device that controls a supply of a first phase fluid flowing through the fuel cell stack. A controller monitors at least one parameter of the fuel cell stack and controls the supply to generate pulses of reactant when the at least one parameter crosses a threshold to flush a second phase fluid from said fuel cell stack.
