Abstract:
1. A hybrid silencer in a fuel cell system, the hybrid silencer comprising: an expansion chamber connected to a predetermined apparatus of the fuel cell system, wherein the expansion chamber reduces acoustic noise of a fluid, which is a blend of a liquid component and a gas component, discharged from the predetermined apparatus; a water-absorber disposed inside the expansion chamber, wherein the water-absorber absorbs the liquid component of the fluid which flows into the expansion chamber from the predetermined apparatus; and a perforated silencer which discharges the fluid, from which the liquid component is removed by the water-absorber, while reducing acoustic noise of the fluid discharged therefrom, wherein the expansion chamber comprises: an inlet pipe which receives the fluid from the predetermined apparatus; and an outlet pipe which discharges the liquid component absorbed by the water-absorber, wherein the water-absorber is in contact with the outlet pipe.
