英文要約Title:The development of a low cost hydrogen storage tank with high strength low alloy steel liner (FY2013-FY2015) FY2013 Annual Report

In order to spread the hydrogen energy, it is very important to decrease the construction cost of the hydrogen filling station. One of the strategies develops the low cost hydrogen storage tank. JFE Steel Corporation and JFE Container Corporation started the development of a low cost hydrogen storage tank with a high strength low alloy steel liner and Carbon fiber reinforced plastic (CFRP) layer.
Those studies as follows were conducted.
1. Trial productions of 9.4L and 30L tanks and various tests.
The tanks with the volume of 9.4L and the liner of 34CrMo4 steel with tensile strength below 950MPa and CFRP layer were manufactured for measurement of burst pursuer and pressure cycle fatigue property. Fatigue life was over 100 thousand cycles. The tanks with the volume of 30L also were manufactured.
2. Production and settings of the pressure cycle test machine
A pressure cycle test machine for evaluation of fatigue life of tanks was introduced.
3. Establishment of the fatigue test with cathodic hydrogen charging
 A fatigue test method with cathodic hydrogen charging was established. By using this method instead of the fatigue test in high pressure hydrogen, it is expected that the study of the effect of hydrogen on fatigue life property is accelerated because many machines can be used for this project.
