Description
Technical Field
The invention relates to the technical field of proton exchange membrane fuel cells, in particular to an automatic fuel cell stacking system.
Background
The proton exchange membrane fuel cell is formed by serially laminating a plurality of single cells and is fastened through an inner positioning screw rod or a clamping strip. To form a fuel cell stack. When the electric pile works, hydrogen and oxygen enter from the inlet respectively and are distributed to the single cell bipolar plates through the main channel of the electric pile, the bipolar plates are uniformly distributed to the electrodes through diversion, and the electrochemical reaction is generated by the contact of the diffusion layer and the catalyst. When the fuel cell is stacked, the pole plates must be mutually pressed to prevent air leakage, and the main gas channels of the pole plates are aligned, so that hydrogen and oxygen can smoothly reach each single cell of the fuel cell. The quality of the fuel cell stack is closely related to the performance of the cell product, and if each single cell is not provided with a good positioning device during assembly, the dislocation during assembly can cause uneven stress of the fuel cell stack, and the sealing performance, the contact performance and the mass transfer performance of the fuel cell stack are influenced, and finally, the output characteristic of the cell is influenced.
At present, the electric pile is generally assembled manually or semi-automatically, components such as a bipolar plate, a membrane electrode, an installation plate and the like are manually stacked on an installation table, and the materials are ensured to be aligned in the stacking process by means of a positioning device. When the nuts are locked, the locking sequence is independently completed, so that the locking sequence and the locking difference exist, the final fastening is difficult to control balance, the upper part and the lower part of the end plate cannot be uniformly pressed down, and the direct mutual pressure of the bipolar plate and the membrane electrode in the stack is difficult to balance; and the bipolar plate and other raw materials have processing errors, and the processing errors can be accumulated during final assembly, so that the uneven stress degree of each part inside the galvanic pile is accumulated and increased. When the contact pressure of some areas in the electric pile is too large, the bipolar plate is easy to deform, and the prepared proton exchange membrane fuel cell is also damaged due to failure; when the contact pressure of some areas in the electric pile is too small, gaps exist among the components such as the bipolar plates and the like, and the fuel cell is not sealed firmly, so that hydrogen and oxygen are mixed, in addition, the contact resistance of the membrane electrode and the bipolar plates is also increased sharply, the internal resistance of the cell is increased, and the performance of the whole fuel cell is finally influenced.
