Abstract
The utility model discloses a fuel cell gas deflector structure. According to the fuel cell gas deflector structure, double gas inlets are adopted for charging a gas, a single gas outlet is adopted for discharging the gas, and a flow channel is a parallel snakelike flow channel. The fuel cell gas deflector structure is characterized in that the double gas inlets supply the gas; the single gas outlet discharges the gas; a flow field is a parallel snakelike flow field; and a flow guide pad is arranged at each of the transition positions between the gas inlets and the flow channel and between the gas outlet and the flow channel; the flow guide pads are made of the same material as a plate body, so that not only a supporting effect is achieved, but also the hydrogenation reaction with a reactant is avoided; the fuel cell gas deflector structure is convenient to machine and assemble; simultaneously, the conductivity of a fuel cell main body is remarkably improved; and each sealing ring has an integrated structure and has an arc-shaped design at each of positions of the gas inlets and the gas outlet.
Description
Technical field:
The utility model relates to a kind of fuel cell gas deflector structure, refers more particularly to a kind of flow field plate structure of PEM hydrogen-air fuel cell, belongs to the fuel cell technology field.
Background technology:
The air admission hole of conventional fuel cell baffler and venthole transition position all are to adopt metallic gasket to support, but owing to metal material has susceptibility-to-corrosion, processing cost is higher, and easy and reactant generation chemical reaction, and then influence the useful life of battery.And the baffler runner usually adopts is the single channel serpentine flow, and the path is longer, and the resistance that gas flow receives is bigger, thereby gas can not be evenly distributed in the flow field, has reduced the generating efficiency of electrode.The utility model provides a kind of fuel cell gas deflector structure; This structural design adopts diversion pads substituted metal pad; Solved metallic gasket not long shortcoming in useful life; And adopt two air admission holes to add the structural design of parallel serpentine flow path, make the performance of Proton Exchange Membrane Fuel Cells that obvious lifting arranged.
Summary of the invention:
The utility model purpose is used the various drawbacks that metallic gasket produced for solving on the conventional fuel cell baffler, and designs a kind of novel fluidic plate structure.
The technical solution of the utility model patent is: a kind of fuel cell gas deflector structure is to adopt two pore air inlets, single pore exhaust, and runner is parallel serpentine flow path.It is characterized in that: two air admission hole air feed, single pore exhaust, the flow field is parallel serpentine flow, air admission hole and venthole and runner transition position are equipped with diversion pads.Diversion pads has adopted the material the same with plate body, has not only played supporting role, has also avoided and reactant generation hydrogenation; Processing and assembling are all more convenient; The battery main body conductance also significantly improves simultaneously, and the as a whole structure of sealing ring designs for arc at the air inlet/outlet place.
The utility model advantage is: avoided and reactant generation hydrogenation, the battery main body conductance also significantly improves, and the reacting gas stress distribution is even, and air-tightness is better.

Specific embodiments:
A kind of fuel cell gas deflector structure is provided by above accompanying drawing:
Fig. 1 is a kind of hydrogen panel body overall construction drawing of fuel cell gas deflector structure: plate body (1), air admission hole (2), air admission hole (3), diversion pads (4), slope (5), parallel serpentine flow path (6), venthole (7), sealing ring (8), diversion pads seal groove (8 '), guiding gutter (9), diversion pads (10), diversion pads (11), parallel channels flow field (12), plate body seal groove (13), gas intersectional region (101).
Below comprehensive accompanying drawing a kind of fuel cell gas deflector structure is further specified.
The anti-hydrogen face that is shown of Fig. 1, reacting gas gets into from air admission hole (2), air admission hole (3), flows through guiding gutter (9); Get into parallel serpentine flow path (6) through slope (5); Gather at last and flow into gas intersectional region (101) and locate, flow out from venthole (7), the periphery of plate body seals through sealing ring (8); Two pore air inlets can reduce the resistance of gas to a great extent through reducing gas stream through the path.
Shown in Figure 2 is air surface, and the structure of air surface is parallel channels flow field (12), becomes 90 degree, sealing ring shape, consistent size that hydrogen face and air surface are used with parallel serpentine flow (6) relative position.
Shown in Figure 3, the structure of diversion pads (4), diversion pads (10), diversion pads (11), diversion pads simultaneously is a guiding gutter (9), another side is a seal groove (8 ').Size can design according to the size of the groove of air inlet/outlet place processing on the plate body, has played the effect of shunting gas, makes gas to get into uniformly in the runner; Its material is consistent with plate body; Seal groove on diversion pads seal groove and the plate body forms an integral body, processing and simple and convenient assembly through diversion pads and plate body assembling back; Avoid taking place hydrogenation, make the life-span of battery obtain prolonging.The structural design of arc sealing ring reduces the dead angle, and the concentrated stress of having disperseed gas has improved sealing property greatly.
