Abstract
A kind of cell of fuel cell belongs to field of fuel cell technology, the more particularly to insulation technology between the yin, yang pole plate of cell of fuel cell；Cell of fuel cell includes：Anode plate, cathode plate, proton exchange membrane, fluid sealant；It is characterized in that：By the edge of the anode plate, cathode plate, it is designed to convex-concave side, and the protrusion at anode plate edge is corresponding with the recessed portion at cathode plate edge, the recessed portion at anode plate edge is corresponding with the protrusion at cathode plate edge；It is formed by groove at the edge of anode plate, cathode plate and proton exchange membrane and coats insulating cement；After the technical program, due to the spacing between anode plate and cathode plate edge, it is the decades of times of the thickness of proton exchange membrane, therefore the probability being short-circuited significantly declines；It is coated with insulating cement simultaneously as being formed by groove at the edge of anode plate, cathode plate and proton exchange membrane, is also beneficial to increase substantially insulation performance.
Description
Technical field
The invention belongs to field of fuel cell technology, the more particularly to insulation between the yin, yang pole plate of cell of fuel cell
Technology.
Background technology
As shown in figure 3, being the conventional structure of prior art cell of fuel cell, cell of fuel cell includes：Anode plate
100, cathode plate 200, proton exchange membrane 300, fluid sealant 400, wherein anode plate 100, cathode plate 200 and proton exchange membrane 300
Edge alignment；Since the thickness S of proton exchange membrane 300 only has tens microns, that is, anode plate 100 and cathode plate 200
Between spacing be equal to tens microns, fraction of dust impurity is likely to cause short between anode plate 100 and cathode plate 200
Road；To solve the problems, such as this, have entitled：A kind of fuel cell pile, application No. is：201510661244.9 patent application,
Insulation sleeve is set in the edge of anode plate 100 and cathode plate 200, can undoubtedly increase cost and assembly difficulty in this way, simultaneously
Since insulation sleeve is compulsory very thin, still there is the possibility of damaged short circuit.
Invention content
The purpose of the present invention is：A kind of technical solution overcoming disadvantages mentioned above in the prior art is provided, cost is not being increased
And in the case of assembly difficulty, the insulation performance between fuel battery double plates is increased substantially.
To achieve the goals above, cell of fuel cell of the invention includes：It is anode plate, cathode plate, proton exchange membrane, close
Sealing；It is characterized in that：By the edge of the anode plate, cathode plate, it is designed to convex-concave side, and the protrusion at anode plate edge
Corresponding with the recessed portion at cathode plate edge, the recessed portion at anode plate edge is corresponding with the protrusion at cathode plate edge.
Further, the convex-concave side can be designed to trapezoidal or triangular structure, can also be designed to sinusoidal shape structure.
Further, it is formed by groove at the edge of anode plate, cathode plate and proton exchange membrane and coats insulating cement.
After the technical program, since the edge convex-concave of anode plate, cathode plate is interlocked, anode plate and cathode edges of boards
Spacing H between edge, is the decades of times of the thickness of proton exchange membrane, therefore the probability being short-circuited significantly declines；Simultaneously as
It is formed by groove at the edge of anode plate, cathode plate and proton exchange membrane and is coated with insulating cement, be also beneficial to significantly carry
High insulating property.
Description of the drawings
Fig. 1 is front view of the bipolar plates edge using the individual fuel cells of trapezium structure；
Fig. 2 is partial perspective view of the bipolar plates edge using the individual fuel cells of trapezium structure；
Fig. 3 is the sectional view of the individual fuel cells of the prior art.
In figure：
Anode plate 100, anode plate protrusion 101, anode plate recessed portion 102, cathode plate 200, cathode plate protrusion 201,
Cathode plate recessed portion 202, proton exchange membrane 300, fluid sealant 400, proton exchange film thickness S, the edge spacing H of bipolar plates.
Specific implementation mode
Fig. 1,2 are the embodiment of the present invention, and the edge of anode plate 100, cathode plate 200 is arranged to trapezoidal convex-concave structure,
And keep anode plate protrusion 101 corresponding with cathode plate recessed portion 202, make anode plate recessed portion 102 and cathode plate protrusion 201
It is corresponding.
Further, it can be formed by groove and coat at the edge of anode plate 100, cathode plate 200 and proton exchange membrane 300
Insulating cement not only improves the adhesive force of reinforced insulation glue, is also beneficial to reinforced insulation performance.
After the technical program, since the spacing H between anode plate 100,200 edge of cathode plate is proton exchange membrane
The decades of times of 300 thickness S, therefore the probability that bipolar plates are short-circuited significantly declines；Simultaneously as in anode plate 100, cathode
Plate 200 and the edge of proton exchange membrane 300 are formed by groove and are coated with insulating cement, are also beneficial to increase substantially insulating properties
Energy.
The present invention is not limited in above-described embodiment, can also carry out various change combination according to the principle of above-described embodiment.
