Abstract:
1. An electrochemical device, comprising: two electrodes including a cathode and an anode; and an electrolyte that is separate and distinct from the two electrodes and is arranged to conduct an ionic current from a first electrolyte surface in contact with one of the electrodes to a second electrolyte surface in contact with the other electrode, wherein the cathode includes a first electrochemically active fluid layer that is disposed over and clings to a first microfeatured fluid-directing structure arranged to engage the electrolyte, wherein the anode includes a second electrochemically active fluid layer that is disposed over and clings to a second microfeatured fluid-directing structure arranged to engage the electrolyte, wherein at least one of the first microfeatured fluid-directing structure and the second microfeatured fluid-directing structure is configured to direct at least one of the first electrochemically active fluid layer according to a first predetermined flow pattern and the second electrochemically active fluid layer according to a second predetermined flow pattern, and wherein the electrolyte includes a reaction product of at least a portion of the cathode with at least a portion of the anode.
