The invention provides a fuel cell vehicle hydrogenation port device and a fuel cell vehicle provided with the same. The fuel cell vehicle hydrogenation port device comprises a hydrogenation port, a first-stage filtering element, a first-stage one-way mechanism, a first-stage pressure stabilizing mechanism, a second-stage one-way mechanism and a second-stage pressure stabilizing mechanism, whereinthe hydrogenation port is connected with the hydrogen supply end and is provided with a channel allowing hydrogen to enter; the first-stage filtering element is arranged in the hydrogenation port andused for filtering the hydrogen entering the hydrogenation port; the first-stage one-way mechanism is arranged at the downstream of the first-stage filtering element to prevent reverse flow of the hydrogen; the first-stage pressure stabilizing mechanism is arranged at the downstream of the first-stage one-way mechanism to balance the pressure of gas passing through the first-stage one-way mechanism; the second-stage one-way mechanism is arranged at the downstream of the first-stage pressure stabilizing mechanism to prevent reverse flow of the hydrogen; and the second-stage pressure stabilizing mechanism is arranged at the downstream of the second-stage one-way mechanism to balance the pressure of the gas passing through the second-stage one-way mechanism. According to the fuel cell vehicle hydrogenation port device, the hydrogenation port is integrated with the two one-way mechanisms and the two-stage pressure stabilizing mechanisms, so that the possibility of failure and leakage of aone-way valve caused by frequent pressure change is reduced, and the pressure fluctuation is better inhibited.
本发明提供一种燃料电池车辆加氢口装置及设置有该装置的燃料电池车辆,该装置包括:加氢端口,与供氢端连接,并设置有供氢气进入的通道;一级过滤件,设置在加氢端口中,对进入加氢端口的氢气进行过滤;一级单向机构,设置在一级过滤件的下游,防止氢气逆向流动;一级稳压机构,设置在一级单向机构的下游,平衡经过一级单向机构的气体的压力;二级单向机构,设置在一级稳压机构的下游,防止氢气逆向流动;及二级稳压机构,设置在二级单向机构的下游,平衡经过二级单向机构的气体的压力。本发明的装置通过将加氢端口与两个单向机构及两级稳压机构整合在一起,降低了由于压力频繁变动而造成的单向阀失效与泄露的可能,并能更好地抑制压力的波动。
