摘要： An apparatus for discharging water in exhaust fluid is disclosed. The apparatus includes a body having an inlet disposed on an exhaust path for exhausting exhaust fluid exhausted from a fuel cell stack to the outside and through which the exhaust fluid is introduced, an outlet communicating with the outside, an interior space allowing the inlet and the outlet to communicate each other, and a discharge passage communicating with the outside to discharge water in the interior space. The apparatus further includes a first resistance unit disposed on a flow path along which the exhaust fluid flows in the interior space and having first fine holes through which at least a portion of the exhaust fluid passes, and a second resistance unit disposed on a discharge path along which the water in the interior space is discharged through the discharge passage and having second fine holes through which the water passes.
