Background
The proton exchange membrane fuel cell is formed by stacking a plurality of single cells in series and is fastened by a positioning screw rod or a clamping strip. And forming a fuel cell stack. When the electric pile works, hydrogen and oxygen enter from the inlet respectively and are distributed to each single cell bipolar plate through the electric pile main channel, the bipolar plates are uniformly distributed to the electrodes by diversion, and electrochemical reaction occurs through the contact of the diffusion layer and the catalyst. When the fuel cells are stacked, the electrode plates are ensured to be mutually pressed to prevent air leakage, and the main gas channels of the electrode plates are ensured to be aligned, so that hydrogen and oxygen can smoothly reach each single cell of the fuel cell. The stacking quality of the fuel cell is closely related to the performance of the cell product, if a good positioning device is not arranged on each single cell during assembly, uneven stress of the fuel cell stack can be caused during assembly, and the sealing performance, the contact performance, the mass transfer performance and the output characteristic of the cell are influenced finally.
The current pile is assembled by manual or semi-automatic, and the bipolar plates, the membrane electrodes, the mounting plates and other parts are stacked manually on the mounting table, so that the materials are ensured to be stacked by means of the positioning device. However, when the nuts are locked, the locking sequence is independently completed, so that the locking sequence and the locking difference are caused, the final fastening is difficult to control balance, the end plates cannot be uniformly pressed down up and down, and the direct mutual pressure between the bipolar plates and the membrane electrodes in the electric pile is also difficult to balance; and machining errors exist in raw materials such as bipolar plates and the like, and the machining errors can be accumulated during final assembly, so that the degree of uneven stress in the 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 proton exchange membrane fuel cell prepared by the bipolar plate is also invalid and damaged; when the contact pressure of some areas in the electric pile is too small, gaps exist among the bipolar plates and other parts, and the fuel cell is not firmly sealed, so that hydrogen and oxygen channeling is caused, in addition, the contact resistance between the membrane electrode and the bipolar plates is also sharply increased, the internal resistance of the cell is increased, and the performance of the whole fuel cell is finally affected.
