Abstract
The utility model relates to an outside plate distributing non-through type cathode current guide plate. The utility model adopts a sealing air distributing main pipe (1) which is arranged outside a polar plate (9). The sealing air distributing main pipe (1) is used for inputting low pressure air to an air distributing way (2) in the polar plate form an inlet of the back of the polar plate (9), then the low pressure air is sent one end of a sealing current guide groove (4) of the front of the polar plate by a connection hole (3) and flows to the other end of the current guide groove, and after the low pressure air joins oxidation reaction, the low pressure air enters an air exhaust way (6) from a connection hole (5) of the other end of the current guide groove and is exhausted with water vapour generated by the oxidation reaction by an exhaust opening (8). The outside plate distributing sending fashion spares the occupied carbon plate area of an air distributing fashion. An effective reaction area can occupy the 70% or over 70% of a cathode plate area. The utility model adopts a non-through type air distributing fashion, and an air guide groove is not directly communicated with an atmosphere on the cathode plate, so the low pressure air is distributed by the back of the cathode plate towards a working surface, the low pressure air returns to the back of the working surface from a reaction region to be exhausted after the reaction. The sealing performance of the sealing area of the non-through working surface is good. The utility model has the advantages of high structure strength and simple structure. The utility model is suitable for the bulk processing production of the carbon plate.
Description
Affiliated technical field:
The utility model belongs to the structure of the cathode diversion plate in the Proton Exchange Membrane Fuel Cells in the new energy field.
Technical background:
A developing direction of fuel cell is to adopt the technological approaches of low temperature, low pressure, be used on the small-power ventilation type fuel cell more, but the low-pressure gas energy is low, volume big, the dispensing difficulty, require bigger gas distribution pipeline area, and the fuel battery pole board of general structure, air (oxidant) hydrogen (fuel) all distribution total pipeline that forms of the through hole from the carbon plate is carried, this will take bigger carbon plate area, reduced the response area of carbon plate, increase cost, increased the structure weight and volume.
The content of utility model:
The purpose of this utility model is thoroughly to change the structure of present fuel battery pole board, and a kind of outer non-through cathode diversion plate of distribution of plate of new structure is provided.
Technical solution of the present utility model is by distribution house steward (1), pole plate (9) guiding gutter (4) is formed, it is characterized in that above-mentioned distribution house steward (1) is arranged on the outside of pole plate (9), and in pole plate (9), be provided with distribution road (2) that is connected with distribution house steward (1) and the air inlet connecting hole (3) that is connected with distribution road (2), and the guiding gutter (4) that is connected with air inlet connecting hole (3), and the steam vent (5) that is connected with guiding gutter (4) reaches the exhaust duct (6) that is connected with steam vent (5), gas enters distribution road (2) successively by distribution house steward (1), air inlet connecting hole (3), guiding gutter (4), exhaust connecting hole (5), exhaust duct (6), and outside exhaust outlet (8) was discharged pole plate (9), the diagonal place in pole plate (9) respectively was provided with a fuel gas air passing hole (7) in addition.
The air intake structure of version of the present utility model is consistent, gathers exhaust but exhaust structure can be a side, also can be opposite side exhaust respectively, also can be the version that exhaust and both sides difference exhaust are gathered in middle air inlet both sides.
The outer non-through cathode diversion plate of distribution of plate has adopted a distribution house steward (1) who installs, seals in pole plate (9) outside, with the low-pressure air of source of the gas input.(the design difference according to baffler can be from 0.3kg/cm
2-0.001kg/cm
2Relative pressure) import from pole plate (9) back side is input to the interior distribution road (2) of pole plate, an end of delivering to the front confined bed chute (4) of pole plate by connect apertures (3) flows to the other end again, after participating in the oxidation reaction generating, reacted air enters the steam that exhaust duct (6) and reaction generate from the connect apertures (5) of the other end and discharges by exhaust outlet (8) together, has finished the whole duty cycle of the outer distribution of pole plate.
The outer dispensing mode of this as can be seen plate is economized the shared carbon plate area of board falling distribution mode, comfort zone can account for pole plate (9) area 70% or higher.
Owing to adopted non-through distribution mode, air conducting groove (4) is directly logical atmosphere on minus plate, and by the minus plate back side to the working face distribution, rotate back into working face from reaction zone again after the reaction and discharge behind.The seal area that does not run through working face, good seal performance, structural strength height, simple in structure are applicable to the processing in enormous quantities of carbon plate.
