Technical Field
The invention relates to the technical field of fuel cells, in particular to a water separator with a novel structure.
Background
The existing water diversion device for the fuel cell can be divided into two types from the basic principle:
(1) separating liquid drops by using centrifugal force, arranging a guide vane or a baffle plate structure or adopting a spiral flow passage in the water separator to induce a gas-liquid mixture to rotate at high speed, and throwing the liquid drops to the inner wall of the water separator and flowing down downstream under the action of the centrifugal force to achieve the purpose of separating the liquid drops from the gas;
(2) by utilizing the adhesion effect of the liquid drops and adopting the structures such as the filter element or the corrugated plate, the contact area between the liquid drops and the peripheral wall surface is increased, so that the liquid drops are adhered to the wall surface to achieve the purpose of separating the liquid drops from the gas.
For the first type of device, considering the water diversion efficiency, the gas-liquid mixture needs to form a swirl and a centrifugal force which are large enough, so the water diverter has relatively fixed size and larger volume, and is not beneficial to improving the arrangement integration applicability and the system volume power density of the water diversion device.

the series tail part water section 7 comprises a series tail main flow pipe 71 and a series tail drainage pipe 72, a series tail air inlet 711 and a
It should be noted that the main fluid flow direction in the parallel tail main flow pipe 61 is referred to herein as the main flow direction of the mixed fluid branched into the parallel tail main flow pipe 61, and specifically, refer to the vertical downward arrow direction in the parallel tail main flow pipe 61 in fig. 8 and 9. Similarly, the main fluid flow direction in the tandem tail main flow pipe 71 as referred to herein refers to the main flow direction of the mixed fluid entering the tandem tail main flow pipe 71, and in particular, the vertical downward arrow direction in the tandem tail main flow pipe 71 can be referred to in fig. 8 and 9.
In addition, in the water separator, the parallel tail reverse drainage pipe orifice 622 and the series tail reverse drainage pipe orifice 722 can perform reverse drainage on the separated gas, so that the gas-liquid separation effect is achieved. The operation principle is the same as that of the reverse-flow-
The working process of the water separator is as follows:
(1) after entering the
(2) Then, the separated gas is reversely drained at the head reverse
(3) Moreover, the mixed fluid passing through the parallel tail reverse flow-guiding pipe orifice 622 in the parallel tail main flow pipe 61 continues to reversely flow the separated gas at the serial tail reverse flow-guiding pipe orifice 722, so that gas-liquid separation is realized.
(4) The separated gas is output from the
Specifically, in the water separator, the pipeline joints are connected through
Fifth embodiment
A fifth embodiment of the present invention provides a water separator,
referring to fig. 11, fig. 11 is a sectional view of a water separator according to a fifth embodiment of the present invention.
The water separator provided in the fifth embodiment of the present invention is different from the water separator provided in the fourth embodiment of the present invention only in that: the water separator provided in the fifth embodiment of the present invention is further provided with an intermediate
Specifically, the intermediate

Sixth embodiment
A sixth embodiment of the present invention provides a water separator.
The water separator provided in the sixth embodiment of the present invention is different from the water separator provided in the fifth embodiment of the present invention only in that: a plurality of middle water distribution sections are sequentially arranged in parallel, so that the pipeline length is prolonged on the basis of the water distributor provided by the fifth embodiment, and more times of flow distribution and reverse flow guiding are realized. Referring to fig. 11, a water separator according to a sixth embodiment of the present invention is provided with a plurality of intermediate
Specifically, a water separator according to a sixth embodiment of the present invention includes:
the two adjacent middle water-dividing
the middle fluid inlet 311, the
the
Seventh embodiment
A seventh embodiment of the present invention provides a water separator.
The water separator according to the seventh embodiment of the present invention is based on the fourth embodiment, the fifth embodiment, or the sixth embodiment, wherein a plurality of serial tail water sections 7 are sequentially arranged in series, and a
In summary, the water separator provided in each embodiment of the present invention does not need structures such as a centrifugal mechanism, a filter element or a corrugated plate, and only needs a pipeline with a nested structure to achieve the water separation effect, so that the water separator has a small volume, a simple structure, high arrangement integration adaptability, and a small flow resistance, and can avoid the risk of performance degradation of the stack due to the blocking of a flow channel caused by the falling of internal materials.
Moreover, the water separator provided in each embodiment of the present invention is designed to be a multi-stage flexible structure on the basis of ensuring good water separation efficiency, so that the number of water separation stages (for example, the number of the middle water separation sections 3) can be increased or decreased according to different arrangement spaces and water separation efficiency requirements, the external dimensions of the water separator can be flexibly adjusted, and even various water separation devices with special-shaped structures can be made, so as to improve the arrangement applicability of the water separator to the greatest extent.
In conclusion, the water separator provided by the embodiment of the invention has the advantages of wide applicability, small flow resistance, pollution prevention and low cost, is simple in structure and convenient to process and assemble, avoids the risks of overlarge flow resistance and possibility of falling off and blocking a flow channel due to an internal structure of the traditional water separator utilizing the adhesion effect of liquid drops, can reduce the cost of a water separator, and can generate better economic benefit.
Bench tests show that the water separator provided by each embodiment of the invention has a good water separation effect.
Eighth embodiment
An eighth embodiment of the present invention provides a fuel cell, in particular a proton exchange membrane fuel cell. The fuel cell is provided with a water separator as provided in any of the embodiments above. Wherein: the stack anode outlet of the fuel cell is connected (preferably by a flexible tube) to the
