Fuel cell as a kind of green device that chemical energy in fuel directly can be converted into electric energy, with efficient
The advantages of rate, high-energy-density and low stain, it is considered to be future replaces one of important novel energy of fossil energy.Wherein, it is double
Pole plate is one of vital part in fuel cell, plays collected current, gaseous fuel distribution, hydro-thermal management and intensity branch
The effect such as support.In fact, the capacity efficiency of fuel cell is heavily dependent on the structure of bipolar plate runner.The runner of high-quality
Structure can improve the flow regime of reactant and product, electrode is in time obtained reactant everywhere, and can be in time
Cooling water is excluded, the generating efficiency of fuel cell is improved.
There are parallel flow field, snake type flow field and interdigitated flow field in common fuel battery double plates flow field.Although parallel flow field
Pressure drop is relatively low, but easily fuel phenomenon pockety in runner occurs, so as to the problem for causing cooling water to be piled up.Serpentine flow
Field has the advantages that drainability is strong, but pressure drop is larger.Interdigitated flow field can promote forced convertion of the fuel in runner, but
Being can be because pressure drop deficiency causes aqueous water in runner top retention problems.
By literature search, publication number is authorized：CN204333116U, a kind of entitled PEM in helical structure flow field
Fuel battery double plates.The utility model provides a kind of dual polar plates of proton exchange membrane fuel cell in helical structure flow field, its
Runner is spirality, and width of flow path is less than each interlamellar spacing width of runner, and tunnel inlets and runner exit are on spiral flow channel
Central Symmetry is distributed.The advantage of the utility model is that reaction gas is evenly distributed with water concentration on whole runner, improves battery
The stability of output performance.But in the utility model, the single track flowing in runner due to fluid, pressure drop is larger, causes flow velocity mistake
Hurry up, hydrogen-oxygen fuel reaction is insufficient.
The content of the invention
The purpose of this utility model is the defect for overcoming prior art to exist, it is effective solve bipolar plate runner pressure drop compared with
Greatly, the problems such as fuel skewness, there is provided a kind of fuel battery double plates in web frame flow field.
To achieve the above object, the technical solution of the utility model is：A kind of fuel battery double plates in web frame flow field,
Including flow channel entry point, sealing ring, bipolar plate, dowel hole, flow field area, annular channel, radial flow path and runner exit.Runner
Entrance, sealing ring, dowel hole, flow field area, annular channel, radial flow path and runner exit are processed on bipolar plate.It is fixed
Position pin-and-hole is located on four angles of bipolar plate.Flow channel entry point, annular channel, radial flow path and runner exit are processed in flow field
Area, flow field area is surrounded by sealing ring, it is characterised in that：Web frame runner is cross-linked group by annular channel and radial flow path
Into symmetrical arrangement.
Preferably, described web frame runner is made up of annular channel and radial flow path, symmetrical arrangement, and
Even arrangement flowing full place.
Preferably, in described web frame runner, annular channel is cross-linked by radial flow path.
Preferably, described runner is introduced to flow field area central area by flow channel entry point, extends from inside to outside, by runner
Outlet is drawn.
The utility model has the advantage of：
(1) web frame runner is symmetrical, and annular channel is cross-linked with radial flow path, has both improved fluid in entirety
Flow regime in flow field, reduces pressure drop, turn avoid the problem that aqueous water is detained in runner.
(2) web frame runner makes full use of conversion zone, improves the reaction efficiency of hydrogen-oxygen fuel.
(3) distribution of web frame runner is compact uniform, and hydrogen-oxygen fuel is more uniform with cooling water distribution, exports battery current
More stablize.
