A dielectric barrier discharge apparatus and module for perfluorocompounds (PFCs) abatement are disclosed. The dielectric barrier discharge apparatus includes a housing, a first dielectric tube disposed in the housing, a second dielectric tube disposed in the first dielectric tube, and at least one electrode disposed in the housing. By this arrangement, a first cooling gas passage is formed between the housing and the first dielectric tube, a PFCs passage is formed between the first and second dielectric tubes, and a second cooling gas passage is formed in the second dielectric tube. While the applied voltage for the electrodes is greater than a breakdown voltage, high energetic electrons generated in the PFCs passage can ionize or dissociate the PFCs further to be removed. Meanwhile, a cooling gas is introduced to the cooling gas passage for cooling the electrodes. A dielectric barrier discharge module composed of a plurality of dielectric barrier discharge apparatuses is provided to promote the capacity of the treatment of PFCs gases.
