ABSTRACT:
According to one embodiment of the present invention, a method of cleaning one or more fluid plenums of an electrode assembly is provided. According to the method, a plurality of fluid ports in communication with the fluid plenum are isolated and differentiated into respective sets of plenum input ports and plenum output ports. The input and output ports are engaged with respective cleaning fluid couplings. A cleaning fluid is directed through the fluid plenum by creating a fluid pressure differential ΔP=PIN−POUTacross the plenum input and output ports. The pressure differential ΔP is large enough to force cleaning fluid from the cleaning fluid supply duct to the cleaning fluid waste duct through the fluid plenum. Additional embodiments are disclosed and claimed.
