A dielectric barrier discharge apparatus and module for perfluorocompound (PFC) abatement. The apparatus includes a housing, 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, PFC passage is formed between the first and second dielectric tubes, and a second cooling gas passage is formed in the second dielectric tube. When the applied voltage for the electrodes is greater than a breakdown voltage, high energetic electrons generated in the PFC passage can ionize or dissociate the PFC to be removed. Meanwhile, 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 PFC gases.
