OG exemplary drawing
 
1. An electrochemical cell comprising:
a first electrode, a second electrode, and an electrolyte membrane disposed therebetween;
a first flow structure adjacent to the first electrode, the first flow structure comprising a first planar surface along a side facing the-electrode;
a second flow structure adjacent to the second electrode, the second flow structure comprising a second planar surface along a side facing the electrode; and
a seal around the second flow structure, wherein the seal surrounds an outermost perimeter of the second flow structure;
wherein a perimeter of the second electrode is entirely within a perimeter of the first electrode;
wherein the first flow structure is configured to withstand higher structural force than the second flow structure;
wherein an area of the first planar surface is larger than an area of the second planar surface; and
wherein the entire seal is located outside a boundary of the second planar surface and within a boundary of the first planar surface.
