Described herein are gas diffusion anodes, electrolytic systems comprising such anodes, as well as methods of using such systems. A gas diffusion anode comprises a current collector, an anode porous base, an anode catalyst layer, and an anode-liquid interfacing layer. During the operation, the anode gas chamber receives hydrogen gas, which flows through the current collector into the anode porous base. The anode porous base provides uniform distribution of the hydrogen gas as well as uniform current density. The anode catalyst layer converts the hydrogen gas into protons and returns electrons, through the anode porous base, to the current collector. Protons are transported by the anode-liquid interfacing layer to an anolyte. This layer also blocks the anolyte from contacting the anode catalyst layer. The anode porous base, anode catalyst layer, and anode-liquid interfacing layer help to prevent the migration of the anolyte into an anode gas chamber.

Owing to the comparatively viscous nature of the slurry, specific accommodations for the electrolyte flowpaths must be made, thereby eliminating problematic reaction areas across certain facings of the solid electrode that might otherwise impede slurry flow and/or degrade performance of the battery. Methods of operating such a battery, storing electrical energy, and other related processes are also contemplated.
