Fuel cell vehicle hydrogenation port device and fuel cell vehicle with same

Abstract

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.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a fuel cell vehicle hydrogenation port device. Background technique [0002] The hydrogenation port of the fuel cell is a prior art, and there are ready-made products, the inside of which is a bottle mouth and a check valve. When the existing hydrogen refueling port is used alone, the hydrogen refueling port will leak due to factors such as excessive external pressure, so it is necessary to add an additional one-way valve at the rear, and the multiple connections increase the number of pipelines and ports. Contents of the invention [0003] In order to solve the above problems, the present invention provides a fuel cell vehicle hydrogen filling port device, which can avoid leakage due to factors such as bottle mouth valves and multiple connection interfaces. [0004] In order to achieve the above purpose, the present application provides a fuel cell vehicle hydrogenation port device,...
