摘　　要：燃料电池车用氢气对气体品质有严格要求,即使在制氢端满足了氢气标准,其在储-输-注过程中也存在引入杂质的风险,因此需要关注氢气制-储-输-注全周期过程引入杂质的风险。对氢气制-储-输-注全周期用橡胶密封材料与金属材料在氢气及高压条件下的相关研究报道进行了综述,明确了临氢材料在使用过程中引入杂质风险的条件及类型。结果表明:橡胶材料及金属材料在氢气制-储-输-注过程涉及的压力、温度条件下因材料老化或与氢气作用产生气体杂质的可能性几乎为零,但存在因橡胶材料变形及金属材料氢脆引入颗粒物杂质的风险。Hydrogen for fuel cell vehicles has strict requirements on gas quality.Even if purified hydrogen meets the hydrogen standard,there is a risk of introducing impurities in the process of storage,transportation and injection.Therefore,attention should be paid to the risk of introducing impurities in the life cycle process of hydrogen production,storage,transportation and injection.In this paper,the relevant research reports of rubber sealing materials and metal materials used in the whole cycle of hydrogen production,storage,transmission and injection under hydrogen and high pressure were summarized,and the conditions and types of the risk of introducing impurities into hydrogen by materials used in the process were defined.The results showed that under the pressure and temperature conditions involved in the hydrogen production,storage,transportation and injection process,the possibility of gas impurities caused by material aging or interaction with hydrogen was almost zero,but there was a risk of introducing particulate impurities due to the deformation of rubber materials and hydrogen embrittlement of metal materials.
