A fluidic pump (108) comprises an electrolyte cavity (110) and a pump outlet (115) fluidically coupled to the electrolyte cavity that are within at least a portion of a fluid guiding structure (105), two electrodes (112, 113) extending from the fluid guiding structure into the electrolyte cavity; and a vapor permeable membrane (120) that prevents an electrolyte (125) in the electrolyte cavity from passing through the pump outlet while allowing gas to flow through the pump outlet.
