A galvanic cell (10) is disclosed. Generally, the cell includes an alkali metal anode (12), which electrochemcially oxidizes to release alkali metal ions, and a cathode (14), which is configured to be exposed to an electrolyte solution. A water-impermeable, alkali-ion-conductive ceramic membrane (20) separates the anode (12) from the cathode (14). Moreover, an alkali-ion-permeable anode current collector (16) is placed in electrical communication with the anode (12). In some cases, to keep the anode (12) in contact with the current collector (16) as the cell (10) functions and as the anode (12) is depleted, the cell (10) includes a biasing member (22) that urges the anode (12) against the current collector (16). To produce electricity, the galvanic cell (10) is exposed to an aqueous electrolyte solution, such as seawater, brine, saltwater, etc. |
