The invention relates to the technical field of fuel cells, in particular to a fuel cell bipolar plate sealing method, a fuel cell and a vehicle, a bipolar plate is provided with a sealing groove, and the bottom of the sealing groove is coated with a primer; the invention aims to solve the problems of high surface roughness and low adhesive strength after adhesive dispensing and curing of the bipolar plate in the prior art through a primer coating process before adhesive dispensing of a sealing element on the bipolar plate. The adhesive layer is formed between the bipolar plate and the sealant, so that the steps are simple and convenient, the operation is easy, the precision requirement of required automatic equipment is not high, and the method is suitable for mass production; the adhesive force can be obviously improved after gluing, the requirement that a sealing element formed by dispensing cannot be damaged during disassembly and assembly during follow-up stack disassembly and rework is met, the cost is reduced, and equipment, labor, time and the like are reduced.

    本发明涉及燃料电池技术领域,具体涉及一种燃料电池双极板密封方法、燃料电池以及车辆,所述双极板开设有密封槽,所述密封槽的底部涂覆有底涂剂;本发明通过在双极板点胶密封件前的底涂涂布工艺,旨在解决现有技术中双极板的表面粗糙度高、点胶固化后粘接力低的问题;通过在双极板和密封胶之间形成一层胶层,步骤简便、易于操作且所需的自动化设备精度要求不高,适合大批量生产;涂胶后能明显提高粘接力,且满足后续拆堆返工时拆装不会损坏点胶形成的密封件的要求,降低成本,减少设备、人工、时间等。
