和文要約和文要約等以下本編抜粋:1.研究開発の内容及び成果等
70MPa 級水素ステーション構成機器に対して、充填時間を考慮した最適化検討と、要素技術開発に取組み、中間目標とした機器コスト等の低減と、低コスト型ステーションの技術確立の見通しを得ることができた。
今後、各機器の実機試作を加速し、実用化のための法規制対応をNEDO 他事業等と連

英文要約 Technologies for components have developed for a station of the primary targeted cost, and trial manufacturing has started for their field introduction.
1. Station modeling, cost estimation, and optimization study (JPEC)
Optimized and skid mount specification was studied, using dynamic simulation as to refueling time. Programming study of hydrogen refueling will be considered in FY2011.
2. 70MPa Class Large Capacity Hydrogen Storage Tanks (JSW)
 Safety demonstration tests on SA723 steel were evaluated and the fatigue life in gaseous hydrogen was proved to be over 1,000,000 cycles. Trial manufacture of “Low cost type storage tank” was conducted. An SA723 cylinder was autofrettaged and almost aimed compressive stress value on the inner surface was confirmed. Acoustic Emission test signal with long duration wave form, which is characteristic under cyclic pressurization by gaseous hydrogen in cracked specimen, was possibly produced by hydrogen fatigue crack.
3. High Pressure Hydrogen Valves (KITZ)
 Based on the design completed to FY2009, trial production and assembly of high pressure hydrogen ball valve (actuators and valves) were carried out. It was confirmed to satisfy the target performance for the completed prototype valves by high pressure hydrogen gas. The difference in durability in helium will be verified in cooperation with HYDROGENIUS (Hydrogen Tribology Team), in the FY2011 research and development plan.
4.High-strength and low-cost materials (JRCM)
 Effective methodology for strengthening and suppress of high-cost-nickel use for cost reduction of austenitic stainless steels are focused to obtain new materials. For the achievements of the target, we shall take 1) solution precipitation and work hardening approaches for the material strengthening and 2) alternative raw elements selection such as manganese. Lab-scaled materials were produced and served to manufacturers, and the obtained data such as SSRT testing was provided to further evaluation.
5. Station control system and control valve (YAMATAKE)
Based on the system hardware and control software specifications for JPEC standard station model, detailed design and implementation including key functional testing using process simulation software were completed. Surface treatment method for valve stem was confirmed to keep sealing performance up to 300,000 cycles through testing under hydrogen atmosphere. The first trial production of a control valve using the material supplied by JRCM achieved an equivalent size to a SUS 316 based product.
