Abstract

The invention relates to a rapid adhesion device for a fuel cell bipolar plate. The fuel cell bipolar plate comprises two monopole plates. The rapid adhesion device comprises a press, conductive plates (2), temperature sensors (5), a temperature controller (6) and a constant-current device (7); the press comprises an upper sliding block (11) and a lower sliding block (12); two conductive plates (2) are respectively arranged on the opposite surfaces of the upper sliding block (11) and the lower sliding block (12); the adhered surfaces of two to-be-adhered monopole plates (3) are coated with adhesives (4); the monopole plates are placed between two conductive plates (2); the temperature sensors (5) are arranged between the conductive plates (2) and the monopole plates (3); the constant-current device (7) is respectively connected with the conductive plates (2) and the temperature controller (6); and the temperature controller (6) is connected with the temperature sensors (5). Compared tothe prior art, the rapid adhesion device has the advantages of simple equipment, small occupied space, low requirement for production investment and the like.

Description

technical field [0001] The invention relates to a fuel cell, in particular to a fast bonding device for fuel cell bipolar plates. Background technique [0002] Carbon-based bipolar plates for fuel cells have good stability and strong processability, especially the characteristics of flexible graphite graphite plates with both artificial graphite and metal plates are the development direction of fuel cell bipolar plates. With the progress of industrialization and commercialization of fuel cells, higher and higher requirements are placed on the production and processing efficiency of bipolar plates, and carbon-based bipolar plates are also facing new challenges. [0003] Since the carbon-based bipolar plate needs to be composed of two unipolar plates, deionized water is passed between the two plates to ensure the working temperature of the stack. This process generally needs to be completed by bonding. Specifically, epoxy resin or an epoxy resin-based polymer adhesive mixed ...
