Description

A kind of fuel cell pack

Technical field

The invention belongs to field of fuel cell technology, more particularly to the current terminal minor structure of fuel cell.

Background technology

Prior art fuel cell includes:End plate, bipolar plates, current-collector, reaction membrane module；The electric current wiring of current-collector Terminal is drawn at end plate, and the lead direction of current wiring terminal can be divided into two kinds：One kind being parallel to end plate extraction, such as specially Profit number is CN201380023030.8, entitled：The patent of current collector component for fuel cell is by current wiring terminal It is arranged in the side of conductive plate, the disadvantage is that the connection type fixed single of connecting terminal, cannot be satisfied the different wiring of user Mode requires, and the direction of its terminal is also dumb；Another kind is vertical and is drawn across end plate, such as Patent No. CN200610038520.7, it is entitled：The patent of pem fuel cell stack is that through-hole is arranged on end plate, by electric current Connecting terminal is directly pierced by from the tapping of end plate, the disadvantage is that connecting terminal occupies the longitudinal space of fuel cell, increases combustion Expect the height of battery, in addition, due to the connecting terminal at bottom plate, is in the underface of fuel cell, wiring is inconvenient.

Invention content

The purpose of the present invention is：A kind of technical solution overcoming disadvantages mentioned above in the prior art is provided, fuel cell is made Connecting terminal, neither increases the height of fuel cell, and can meet the different modes of connection requirement of user, and the direction of its terminal Also it can flexibly be arranged, facilitate wiring.

To achieve the goals above, fuel cell pack of the invention includes：End plate, bipolar plates, current-collector, reaction film group Part；It is characterized in that：Further include terminal assemblies, the terminal assemblies include switching contact, conducting wire, the output end being sequentially connected electrically Son；It is provided with blind hole on one side in the end plate, and the wire guide of the blind hole inner wall is provided through at the edge of end plate；By institute The switching contact for stating terminal assemblies is arranged in the blind hole of end plate, and the wire guide in end plate is arranged in the conducting wire, leading-out terminal In；The current-collector includes conductive plate, collects electrical contact, and the collection electrical contact is opposite with the switching contact in end plate blind hole It answers.

Further, both can one wire guide being connected to blind hole only be set at a certain edge of end plate, can also holding The both sides of plate, three while or each one wire guide being connected to blind hole of setting when four.

Further, in the terminal assemblies, a leading-out terminal both can be only set, two, three or four can also be arranged A leading-out terminal, and be electrically connected each leading-out terminal with switching contact respectively by conducting wire.

Further, the leading-out terminal can be arranged to the forms such as jack, contact pin, line ear, threaded hole, stud.

Further, the collection electrical contact, switching contact, can be such as the combining form using plug, socket；

Alternatively, set the collection electrical contact to soft material electric conductor, such as conductive paste, soft carbon paper, it correspondingly will switching Contact is set as solid flush configuration, and is contacted using face with the conducting paste, soft carbon paper.

After the technical program, neither increase the height of fuel cell pack, and the different modes of connection of user can be met It is required that and the direction of its terminal also can flexibly be arranged, facilitate wiring.
