Pressure, they, which accumulate, generates high pressure formation physically fuel cell pack.
Proton exchange membrane is the critical component of low-temperature fuel cell.Therefore, such fuel cell is often abbreviated as
PEM- fuel cell.The common used material of the film is perfluorosulfonicacid (PSFA), famous brand name NafionTM.It
It is the acidic-group in PSFA, it provides enough water in PEM fuel cell and PSFA, to ensure good Proton conducting
Rate.Therefore water is important element in Proton Exchange Membrane Fuel Cells, the selection, design and process control of the regulation of water in material
In be affected.
Hydrogen and oxygen reactants in air are sent to Proton Exchange Membrane Fuel Cells.High power density fuel cell needs
High reactant flow is wanted, sufficiently to meet energy demand.A large amount of hydrogen and air are sent to fuel cell pack, these gases
Need pre- pretreatment, with prevent reactor be subcooled or it is over-drying.This pretreatment is usually to be carried out by external equipment, is led to
Frequently referred to humidifier.The example of passive type humidifier is illustrated in US2017346110 and US2017084935.
The dynamical type or active devices illustrated in CN204759258.In these cases, humidifier is located in fuel cell pack
Neighbouring auxiliary device.A kind of different method is illustrated in CN103915638.Disclosure sets forth a kind of implementable cases
Example, in this case, humidifier becomes a component part of fuel cell pack.It reduces the quantity of pipeline, but it is still
It is the ancillary equipment of fuel cell pack core.It need interface board and and rearrange the path of gas, increase
The volume of battery pile.

Humidifier section in one plane.
Each monocell in fuel cell pack is individually humidified containing it, therefore forms a set of integrated and compact solution
Certainly scheme.Followed by detailed description of the invention.
Gas in battery pile passes through central tube, then by distributing manifold, is directed to flow channel.The design of the two
All ensure that gas is evenly distributed to flow channel, to obtain maximum performance.
Distribution portion is designed to electrochemicaUy inert and electrochemical function, is conducive to gas distribution and adjusts.Part packet
Water can be transferred to the other side from the side of membrane electrode by film containing water guide.The design uses counter-current flow mode.From cathode
Product water mix in the offgas, water will collection sending into pipeline.Corresponding with cathode outlet is anode inlet.Cathode goes out
The product water contained in gas can be used to humidify water guide film.Entrance is transported to hydrogen and can be used in the another side of film
To humidify dry hydrogen.The hydrogen of the part also pre-heating intaking mouth, makes the gas reach ideal electrochemical reaction condition.
Same process occurs in the other end.Hydrogen consumption, therefore increase the moisture of gas.Water passes through proton exchange membrane
Diffusion be active region increase hydrogen in water content another mechanism.During anode output, moist hydrogen is reached
Anode export has simultaneously humidified water guide film.The another side of the wet film is distributed to air intake, therefore is humidified and had adjusted entrance sky
Gas.
The advantage of the invention is that it is fully integratible into fuel-cell single-cell design.It does not need to rearrange required
