Abstract
The invention relates to a fuel cell, which is a method solving vertically placed vehicle fuel cell deflection of single cell structure, a bipolar plate of the assembling cell stack and corresponding positions on two perpendicular edges of MEA are equipped with grooves with same size, and the grooves are placed with insulated support plates sizable to the grooves. The original fuel cell stack structure and assembling method are maintained, the bipolar plate and the MEA structure are slightly changed to solve the stack deflection phenomenon after the fuel cell stack operates for a period of time, so as to improve fuel cell reliability.
Description
Technical field
The present invention relates to fuel cell pile, specifically a kind of method that solves the downwarp of vehicle fuel battery pile.
Background technology
Fuel cell be a kind of isothermal directly chemical energy is converted into the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of electric energy by electrochemical means.Therefore it be not subjected to the restriction of Carnot cycle, energy conversion efficiency height, environmental friendliness without the overheated machine process.Because above these outstanding advantages, the research and development of fuel cell technology in the last few years are the attention of national governments and major company extremely, the cleaning that is considered to the 21 century first-selection is generation mode efficiently.
The modes of emplacement of bipolar plates and MEA is perpendicular to the ground in the vehicle fuel battery pile at present.Because gravity and oscillating action are subjected to restrictions such as assembling mode, clamping force and sealing means, pile bipolar plates and MEA the downwarp phenomenon can occur after operation a period of time, influence the pile operational reliability concerning fuel cell system.Therefore be necessary by the improvement on the pile package assembly, solve pile downwarp phenomenon.
Summary of the invention
The present invention has purpose to be to provide a kind of method that solves the vertical vehicle fuel battery downwarp of placing of single pool structure. on the basis that does not change existing vehicle fuel battery pile modes of emplacement and assemble method, only the structure of part parts is done small change, thereby realize solving the purpose of pile downwarp.On the basis that guarantees fuel cell pile assembling and structure, make full use of existing structure, improve the fuel cell operation reliability.
For achieving the above object, the technical solution used in the present invention is:
A kind of method that solves the vertical vehicle fuel battery downwarp of placing of single pool structure, correspondence position on two vertical edges of the bipolar plates of assembled battery pile and MEA is provided with the groove of same size, is placed with in groove and the sizable insulation support plate of groove.
Arranged outside at insulation support plate has the pressure beam, and pressing beam to press close to the insulation support plate side is the plane, and opposite side is an arc-shaped concave, is provided with the fastening screw of fuel cell pile assembling usefulness in the arc-shaped concave; Described groove is arranged at the same position of bipolar plates and MEA, and it is a rectangular recess.
The present invention has following advantage:
1. change less to original fuel cell structure.The present invention and utilizes existing structure on the basis of existing vehicle fuel battery electric pile structure, only increased insulation support plate and promptly solved pile downwarp phenomenon.
2. do not increase existing fuel cell bulk.The present invention only correspondence position on two vertical edges of the bipolar plates of assembled battery pile and ME is provided with the groove of same size, does not increase existing fuel cell bulk.
3. solve vehicle fuel battery pile downwarp phenomenon, increase the fuel cell operation reliability.
Description of drawings
Fig. 1 is the package assembly schematic diagram of existing fuel cell pile;
Fig. 2 is the downwarp phenomenon schematic diagram of fuel cell pile, and Δ is the downwarp amount among the figure;
Fig. 3 is for improving the package assembly schematic diagram of back fuel cell pile;
Fig. 4 is for improving the trimetric drawing of back fuel cell pile;
Among the figure: 1 is front end-plate, and 2 is fastening screw, and 3 is end plate, and 4 is potted line (groove), and 5 is bipolar plates and MEA, and 6 is insulation support plate, and 7 for pressing beam.
Embodiment
Increase the rectangular recess of same size as shown in Figure 3, Figure 4 at two vertical edge same positions of bipolar plates and MEA5, pile assembling back adds a rectangle engineering plastics insulation support plate 6 at groove, the thickness of insulation support plate is by the degree of depth decision of rectangular recess, and length is suitable with pile length.Arranged outside at insulation support plate 6 has the beam 7 of pressure, and pressing beam 7 to press close to insulation support plate 6 sides is the plane, and opposite side is an arc-shaped concave, is provided with the fastening screw of fuel cell pile assembling usefulness in the arc-shaped concave.On the assembling screw rod, install and press beam 7, be used for fixing insulation support plate.Wherein insulation support plate 6 is installed when fuel cell is assembled with pressing beam 7.
Claims (2)
1. one kind solves the method that vehicle fuel battery is piled downwarp, it is characterized in that: the correspondence position on two vertical edges of the bipolar plates of assembled battery pile and MEA (5) is provided with the groove of same size, is placed with in groove and the sizable insulation support plate of groove (6); Arranged outside at insulation support plate (6) has pressure beam (7), and pressing beam (7) to press close to insulation support plate (6) side is the plane, and opposite side is an arc-shaped concave, is provided with the fastening screw of fuel cell pile assembling usefulness in the arc-shaped concave.
2. in accordance with the method for claim 1, it is characterized in that: described groove is arranged at the same position of bipolar plates and MEA, and it is a rectangular recess.
