Abstract: An electrode assembly can include a reservoir defining a plurality of openings on a first surface of the reservoir, a wicking material extending through one or more of the plurality of openings, and a conductive terminal. An electrode assembly can include a reservoir cap, a reservoir bottom configured to fit to the reservoir cap and define a reservoir therewith, an electrode disposed within the reservoir, and a wicking element in electrical communication with the electrode and configured to absorb a fluid, wherein at least a portion the wicking element is configured to protrude from the reservoir bottom.
