Analysis of Failure Mechanism Hydrogen Fuel Cell Vehicle Refueling Receptacle
With the development of fuel cell vehicle,the service life issue of the refueling receptacle of fuel cell vehicle has been gradually became a focus.Under the specific pressure and temperature conditions,hydrogen molecules can diffuse into the metal causing a decrease in material strength and embrittlement,and leading to the refueling receptacle failure and the hydrogen leakage accidents.In addition,the hydrogen leakage accidents may also be caused by the service life of the refueling receptacle and the loose of the connections.The suffocation,frostbite,burns,and impact injuries may be caused by the hydrogen leakage.The accidental leakage,ignition(or spontaneous combustion),detonation,and explosion are included by the typical hydrogen leakage accidents,which seriously affect the safety of drive,personnel and vehicle.In order to accelerate the commercialization process of the fuel cell vehicles,it is necessary to study the failure mechanism of the refueling receptacle of fuel cell vehicle.Firstly,the failure mechanism of the refueling receptacle of fuel cell vehicle was briefly summarized from four aspects of the vibration in the vehicle operating condition,the high and low temperature cross cycle,the charge discharge cycle,and the hydrogen embrittlement.Secondly,the failure prevention measures of the refueling receptacle of fuel cell vehicle were introduced.Finally,the future technological development trend of the refueling receptacle of fuel cell vehicle was prospected.
