The drawbacks and disadvantages of the prior art are overcome by an electrode fluid distributor. The electrode fluid distributor comprises a fluid passageway having a first end with an inlet and a second end with an outlet. A baffle is included that diagonally traverses the fluid passageway from the first end to the second end, and from a base of the fluid passageway toward an at least partially open side of the fluid passageway. The baffle defines at least a portion of a first reservoir and at least a portion of a second reservoir, with the inlet defining at least a portion of one end of the first reservoir and the outlet defining at least a portion of one end of the second reservoir. The inlet is in fluid communication with the outlet over the baffle. The first reservoir has a width proximate the open side which is smaller proximate the inlet than proximate the outlet.
