Abstract
An electrochemical cell includes a permeable fuel electrode configured to support a metal fuel thereon, and an oxidant reduction electrode spaced from the fuel electrode. An ionically conductive medium is provided for conducting ions between the fuel and oxidant reduction electrodes, to support electrochemical reactions at the fuel and oxidant reduction electrodes. A charging electrode is also included, selected from the group consisting of (a) the oxidant reduction electrode, (b) a separate charging electrode spaced from the fuel and oxidant reduction electrodes, and (c) a portion of the permeable fuel electrode. The charging electrode is configured to evolve gaseous oxygen bubbles that generate a flow of the ionically conductive medium. One or more flow diverters are also provided in the electrochemical cell, and configured to direct the flow of the ionically conductive medium at least partially through the permeable fuel electrode.
