The fuel cell that the present invention proposes, its design principle is:
With corresponding flow field, active region part, be arranged side by side a plurality of parallel fluid channels, and runner be divided into two groups according to identical distance; End at runner is provided with an import and an outlet, at the other end import and an outlet is set also simultaneously.One group of runner at one end pools together, and the connection that links to each other with an import, also pools together at the other end simultaneously, and is connected with an outlet, so just forms the runner that one group of character is equal to; In the same way, another group runner is compiled at head end and end, and be connected with another import and outlet respectively, so just form the runner that second group of character is equal to.In two groups of runners fluid is flowed by opposite direction, this has just formed the interior adverse current of plate of fluid.Two groups of runners are not connected on flow-field plate.At inlet side (or outlet side), one group of runner compiles in the bipolar plates front, is connected with import (or outlet) then; At outlet side (or inlet side), this group runner formerly by penetrating the via hole of bipolar plates, compiles at the flow-field plate back side then, is connected with outlet (or import) more at last.Another group is taked identical measure.Can realize that like this two groups of runners are not connected on flow-field plate.To in above-mentioned two groups of runners arbitrary group all can set up import or export, all can further divide into groups to arbitrary group of runner, but should guarantee that each runner in the same big group of runner is identical at the flow direction at identical flow process place, and different big group runner is opposite at the flow direction at identical flow process place.
Fig. 2 and Fig. 3 are respectively the right view and the left view of air flow field plate 3 among Fig. 1.As Fig. 3, in the front of air flow field plate, parallel runner is divided into two groups by dextrosinistral odd even order: first group of air flow channel 12 and second group of air flow channel 20; Have two air intlets and two air outlet slits at the two ends up and down of flow-field plate, the right side, upper end is first air intake 8, and the left side, upper end is second air outlet slit 7, and the right side, lower end is second air intake 17, and the left side, lower end is second air outlet slit 18.Front in flow-field plate, air enters first group of air flow channel 12 from first air intake 8 through first group of air intake groove 10 and first group of air intake distributing trough 11, and then arrive the back side of flow-field plate through first group of air via hole 13, after first group of air outlet slit collector groove 24 and first group of air outlet slit groove 25 on the flow-field plate back side arrive first air outlet slit 18, this has formed one group of circulation of air path from top to bottom; Front in flow-field plate, air enters second group of air flow channel 20 from second air intake 17 through the second air intake groove 15 and second group of air intake distributing trough 14, and then arrive the back side of flow-field plate through second group of air via hole 21, after second group of air outlet slit collector groove 23 and second group of air outlet slit groove 22 on the flow-field plate back side arrive second air outlet slit 7, this has formed one group of circulation of air path from top to bottom; Because of in two groups of circulation of air paths, being the adverse current state, so reversible flow field in their common formation plates.
In two groups of circulation of air paths, air also can flow to same direction, thereby forms concurrent flow in the plate.Like this, in the reversible flow field, air both reversible flow flows in a plate, but also concurrent flow.
In fuel cell, the air flow field back side of a unit will link together with the fuel flow field back side of another unit, for preventing that two kinds of flow fields from connecting, should on two groups of air outlet slit collector grooves on the air flow field back side and two groups of air via holes, add cover plate, to carve two slot covers overleaf, i.e. the first air flow field plate slot cover 26 and the second air flow field plate slot cover 27 for this reason.
On the air flow field plate, also be carved with two fuel inlets and two fuel inlets, as shown in Figure 3 and Figure 4, this is for reversible flow field in reversible flow field and the fuel slab in the air plates (as Fig. 4 and Fig. 5) integrated.
Fig. 4 and Fig. 5 are respectively the right view and the left view of fuel flow field plate 5 among Fig. 1.As Fig. 5, in the front of fuel flow field plate, parallel runner is divided into two groups by dextrosinistral odd even order: first group of fuel flow channel 38 and second group of fuel flow channel 41; Have two fuel inlets and two fuel outlets at the two ends up and down of flow-field plate, the right side, upper end is first fuel inlet 6, and the left side, upper end is second fuel outlet 9, and the right side, lower end is second fuel inlet 19, and the left side, lower end is first fuel outlet 16.Front in flow-field plate, fuel enters first group of fuel flow channel 38 from first fuel inlet 6 through first group of fuel inlet groove 36 and first group of fuel inlet distributing trough 37, and then arrive the back side of flow-field plate through first group of fuel via hole 31, after first group of fuel outlet collector groove 32 and first group of fuel outlet groove 33 on the flow-field plate back side arrive first fuel outlet 16, this has formed one group of fuel flow path footpath from top to bottom; Front in flow-field plate, fuel enters second group of fuel flow channel 41 from second fuel inlet 19 through second group of fuel inlet groove 40 and second group of fuel inlet distributing trough 39, and then arrive the back side of flow-field plate through second group of fuel via hole 30, after second group of fuel outlet collector groove 29 and second group of fuel outlet groove 28 on the flow-field plate back side arrive second fuel outlet 9, this has formed one group of fuel flow path footpath from top to bottom; Because of in two groups of fuel flow path footpaths, being the adverse current state, so reversible flow field in their common formation plates.
In two groups of fuel flow path footpaths, fuel also can flow to same direction, thereby forms concurrent flow in the plate.Like this, in the reversible flow field, fuel both reversible flow flows in a plate, but also concurrent flow.
In pile, the fuel flow field back side of a unit will link together with the air flow field back side of another unit, for preventing that two kinds of flow fields from connecting, should on two groups of fuel outlet collector grooves on the fuel flow field back side and two groups of fuel via holes, add cover plate, to carve two slot covers overleaf, i.e. the first fuel flow field plate slot cover 34 and the second fuel flow field plate slot cover 35 for this reason.
On fuel flow field plate, also be carved with two air intlets and two fuel inlets, as shown in Figure 4 and Figure 5, this is for reversible flow field in reversible flow field and the air plates in the fuel slab (as Fig. 2 and Fig. 3) integrated.
