This paper presents FRP cylinder for storing high pressure hydrogen gas with Cr-Mo steel liner and Carbon Fiber FRP. Specifically, it relates to an FRP cylinder using a thin Cr-Mo steel liner of thickness 3. 2mm which shows light-weightness same as Al liner FRP. This steel named 34CrMo44 is modified 34CrMo4: No. 17220, specified in EN-10083-3 (2006) and it contains 0. 3 to 0. 6% Mo and not contains intentionally adding Ni. <br>The 34CrMo44 steel shows good resistance to hydrogen embrittlement, especially excellent fatigue crack growth characteristic under high pressure hydrogen gas conditions. Thereby, 34CrMo44 liner FRP has suitability for a high pressure hydrogen accumulator cylinder in station or on-board tank for fuel cell vehicle.
