PROBLEM TO BE SOLVED: To provide a fuel-cell vehicle discharge device that suppresses scattering of generated water liquefied in a gas-liquid separation unit to the rear of a vehicle.SOLUTION: A gas-liquid separation unit 22 includes an upper stage housing 30 having an upper stage chamber 38, a lower stage housing 50 having a lower stage chamber 58, and a first communicating port 60 and a second communicating port 61 that communicate the upper stage chamber 38 and the lower stage chamber 58. The upper stage housing 30 discharges liquid generated water produced by liquefying steam contained in off-gas to the lower stage chamber 58 through the first communication port 60 and discharges the off-gas to the lower stage chamber 58 through the second communication port 61 located behind the first communication port 60. The lower housing 50 includes a lower stage partition plate 91 that performs partitioning into a first lower stage chamber 58A that communicates with the first communication port 60 and a second lower stage chamber 58B that communicates with the second communication port 61 positioned behind the first lower stage chamber 58A, a drain port 64 that discharges the liquid generated water from the first lower chamber 58A, and an exhaust port 65 that discharges the off-gas from the second lower chamber 58B into the atmosphere.SELECTED DRAWING: Figure 10
【課題】気液分離ユニットで液化した生成水が車両の後方に飛散することを抑える燃料電池自動車用排出装置を提供する。【解決手段】気液分離ユニット22は、上段室38を有する上段ハウジング30と、下段室58を有する下段ハウジング50と、上段室38と下段室58とを連通する第1連通口60および第2連通口61とを備える。上段ハウジング30は、オフガスに含まれる水蒸気を液化させた液状の生成水を第1連通口60を通じて下段室58に排出し第1連通口60の後方に位置する第2連通口61を通じて下段室58にオフガスを排出する。下段ハウジング50は、第1連通口60に連通する第1下段室58Aと第1下段室58Aの後方に位置する第2連通口61に連通する第2下段室58Bとに仕切る下段仕切り板91と、第1下段室58Aから液状の生成水を排出する排水口64と、第2下段室58Bからオフガスを大気中に排出する排気口65とを有する。【選択図】図10
