项目摘要
A fuel-cell systems without carbon dioxide emissions are a one of the promising technique for prohibiting a global warming. In case of a fuel-cell vehicle(FCV), high-pressure H_2 gas, up to 70 MPa, is indispensable for a long running range. Although there are lot of paper for studying a hydrogen embrittlement(HE), there are few paper referred to the effect of high-pressure H_2 on the HE phenomenon.In this study, an effect of high-pressure H_2 gas on fatigue properties of several types of structural metallic materials were investigated by means of internal high-pressure H_2 gas technique. And a validity of this technique was confirmed.
无二氧化碳排放的燃料电池系统是防止全球变暖的一种有前途的技术。对于燃料电池汽车(FCV)来说,要实现长距离行驶,高压氢气(高达70 MPa)是必不可少的。本文采用内高压H_2技术研究了高压H_2对几种金属结构材料疲劳性能的影响。并证实了该技术的有效性。
