Description
Technical field
The utility model belongs to fuel cell power generation field.
Background technology
Fuel cell is a kind of energy conversion device, it by electrochemical principle isothermal the chemical energy that is stored in fuel and oxidant is converted into electric energy.Proton Exchange Membrane Fuel Cells (proton exchangemembranefuelcell, PEMFC) be taking perfluorinated sulfonic acid type solid polymer as electrolyte, platinum/charcoal or platinum-ruthenium/charcoal are eelctro-catalyst, hydrogen or purification reformed gas are oxidant, are bipolar plates with the graphite of flow channel or the metallic plate of surface modification.Its reaction principle is that the hydrogen in anode catalyst layer, under catalyst action, electrode reaction occurs, the electronics that electrode reaction produces arrives negative electrode through external circuit, hydrogen ion arrives negative electrode through proton exchange membrane, and oxygen and hydrogen ion and electronics are at the negative electrode generation water that reacts.The output voltage of the typical fuel cell of one joint is about 1 volt, conventionally more piece fuel cell is integrated to series connection formation fuel cell pack in order to reach a higher voltage.Fuel cell unit and air (oxygen) feed system, hydrogen feed system and cooling system composition fuel cell generation powering load.Because Proton Exchange Membrane Fuel Cells is (as high in energy conversion efficiency except having the general characteristic of fuel cell, environmental friendliness etc.) outside, also have and can start fast in room temperature simultaneously, without electrolyte loss, water is easily discharged, life-span is long, the outstanding features such as specific power and specific energy height, therefore it not only can disperse power station for building, suitable to especially removable power source, be electric motor car and do not rely on air to advance one of ideal candidates power supply of submarine, it is army, a kind of Novel moveable power supply that the people are general, at the hydrogen energy era using hydrogen as main energy carrier in future, it is best family power source.
In prior art, multiple monocells are connected together by stacked mode, composition fuel cell pack, by end plate, pull bar and nut, fuel cell pack is tightened together, this mode can make the electrode of fuel cell reator body fully contact with bipolar plates on the one hand, uniform stressed, reduces the internal resistance of whole fuel cell pack, can improve on the other hand the resistance to shock of fuel cell pack.But in order to ensure that fuel cell pack pull bar meets fuel cell pack assembling power and requires and insulating requirements, the overall dimension of above-mentioned end plate reserves sufficient size will to fuel cell pack pull bar and nut, thereby its size will obviously be greater than the overall dimension of monocell, there are two shortcomings in this structure, the one, Tiebar structure takies larger space, affects the volumetric specific power of battery pile; The 2nd, electrode and bipolar plates, in stacked pressing process, easily produce dislocation, affect sealing and the performance of battery pile.
Utility model content
Technical problem to be solved of the present utility model is to provide a kind of end plate of fuel cell pack, can ensure under the condition that assembling requires, reduce the volume of fuel cell pack, and avoid fuel cell pack electrode and bipolar plates to misplace in stacked and pressing process by outside frock, cause battery pile sealing and hydraulic performance decline.For this reason, the utility model proposes following technical scheme: a kind of end plate of new fuel cell heap, comprise the two symmetrical prescription holes of the two minor face inner sides that are located at rectangular slab, it is characterized in that: 8 dark grooves are distributed in four limits of rectangular slab symmetrically, and 6 shallow grooves are distributed in two long limits of rectangular slab symmetrically, and staggered with dark groove.The two symmetrical prescription holes that are located at two minor face inner sides of rectangular slab add up to 6, are shaped as rectangle.
Adopt the end plate of the new fuel cell heap of technique scheme, by fluting and the fixing mode of bandage, reduce the overall volume of fuel cell pack, leave equally distributed outside fix groove, can realize the location, outside in fuel cell pack assembling process, reduced the problem of misalignment that battery pile occurs in assembling process, this scheme has saving material, reduce costs, simple in structure, realize the advantages such as convenient.

Embodiment
From Fig. 1 to Fig. 3, can find out the consisting of of fuel cell pack of prior art:
I: fuel cell pack end plate
II: fuel cell pack pull bar (bolt and nut pair)
4-1: fuel cell pack air ports
4-2: fuel cell pack cooling fluid is imported and exported
4-3: fuel cell pack hydrogen is imported and exported
5: monocell
This fuel cell pack connects together multiple monocells 13 by stacked mode, by end plate I, pull bar II, be that bolt and nut adjutant fuel cell pack tightens together, this mode can make the electrode of fuel cell reator body fully contact with bipolar plates on the one hand, uniform stressed, reduce the internal resistance of whole fuel cell pack, can improve on the other hand the resistance to shock of fuel cell pack.But for ensureing that fuel cell pack pull bar II meets fuel cell pack assembling power and requires and insulating requirements, it is that bolt and nut pair reserves enough sizes that the overall dimension of above-mentioned end plate I will be given fuel cell pack pull bar II, thereby its size will obviously be greater than the overall dimension of monocell 5.There are two shortcomings in this structure, and the one, Tiebar structure takies larger space, affects the volumetric specific power of battery pile; The 2nd, electrode and bipolar plates, in stacked pressing process, easily produce dislocation, affect sealing and the performance of battery pile.
Fig. 4 expresses the structure of the fuel cell pack of the utility model fuel cell pack end plate to Fig. 6:
1: fuel cell pack end plate
