The method includes combining reactants in an electrochemical conversion reaction to produce an electric current and water, and conveying at least some of the water through a water transport unit that is coupled to {TAIL ~ the fuel cell} such {HEAD ~ that water} can be exchanged between the water transport unit and the fuel cell
