1. A stack system comprising:
multiple cells and associated plate structures arranged in a stack;
wherein a plate structure of the multiple cells and associated plate structures has a non-planar, three-dimensional shape, and comprising:
a circumferential end and a center end, wherein the circumferential end and the center end are vertically offset;
a wall structure extending between and connecting the circumferential end and the center end;
a plurality of curving fluid channels on the wall structure extending between the circumferential end and the center end, wherein the plurality of curving fluid channels include a first set of curving fluid channels on one side of the wall structure extending between the circumferential end and the center end, and a second set of curving fluid channels on another side of the wall structure extending between the circumferential end and the center end; and
the circumferential end including multiple outer fluid transport openings through the plate structure, and the center end including multiple inner fluid transport openings through the plate structure, wherein one or more outer fluid transport openings of the multiple outer fluid transport openings and one or more inner fluid transport openings of the multiple inner fluid transport openings facilitate, at least in part, flow of a fluid across the plate structure between the vertically offset circumferential end and center end, through the plurality of curving fluid channels.
