The invention discloses an automatic glue dispensing-based two-polar-plate bonding system which is used for automatic material feeding, glue dispensing and bonding treatment between a first polar plate and a second polar plate. The system comprises a first material feeding device for feeding the first polar plate, a glue dispensing device for dispensing glue to the first polar plate, a second material feeding device for feeding the second polar plate, and a bonding device for bonding the second polar plate to the first polar plate, wherein the material feeding direction of the first material feeding device is perpendicular to that of the second material feeding device. Due to the first material feeding device, the glue dispensing device, the second material feeding device and the bonding device which are connected in sequence, the technical processes of automatic material feeding of each single polar plate, and automatic glue dispensing and bonding of the two polar plates are realized, and no manual assistance is needed; the material feeding direction of the first material feeding device is perpendicular to that of the second material feeding device, so that the production space is saved.
