英文要約1. Safety evaluation for hydrogen storage system of fuel-cell vehicles
The research task and the test procedure necessary for decision of "technical standard of the 70MPa compressible hydrogen gas cylinder for vehicle" were conducted with Japan Automobile Manufacturers Association, etc.
Furthermore, the heat stress of the CFRP hydrogen cylinder was simulated by FEM model, the computing model with high accuracy was developed.
2. Safety evaluation for fuel-cell vehicles
Risk for ships carriage of hydrogen vehicles ( ex. the hazard due to blowout of hydrogen owing to the activation of PRD's of hydrogen cylinders, which might happen when cylinders were heated by radiating heat from the gas-tight deck which was heated by a fire below that deck, etc) was investigated by examinations and the numerical simulation. The results of these investigations were applied to discussion of the ships carriage. Furthermore, the propane burner was developed in accordance with the localized fire test procedure - flame impingement on hydrogen storage cylinders -, and the localized fire test of the type 3 cylinder using this burner was executed.
On the other hand, the proposal to examine the alternative gas of the hydrogen filled to the storage cylinder by the bonfire test, and the research task and the test procedure to the correspondence after the collision and the accident of a fire were conducted.
3. International Standardization
For the international standardization activities on fuel cell vehicles JARI organized FCV steering committee with experts. To proceed international standardization activity effectively, JARI organized safety standardization WG, high pressurized hydrogen standardization WG, fuel quality standardization WG, performance WG, terminology standardization WG and fueling protocol SWG to discuss making drafts and comments on international standard.
Summary of progress:
ISO/TC197 (hydrogen technology): For WG5 (fuelling connector) 1st-DIS17268 (fuelling connector standard including 70MPa geometry proposed from Japan) was denied in June 2010. To breakthrough the conflict chair of TC197 recommended WG5 to ballot 2nd-DIS with another 70MPa geometry proposed from Germany. Japanese stakeholders considered the first priority to have single standard on 70MPa geometry and agreed this recommendation.
For WG6 (hydrogen tank on board) JAMA made a strategy to publish UN-ECE/WP29/AC3 HFCV gtr then publish ISO 15869 harmonized with gtr. JARI proposed ISO/TC197/WG6 to hermonize with gtr at Tokyo meeting in March 2011. To proceed effective discussion JARI joined SAE (society of automotive engineers) meetings.
For WG12 (hydrogen quality), Japan is taking the convener of working group and JARI supported him as secretary. ISO/TS14687-2 for early stage of FCV was published in 2008 then JARI moved to DIS14687-2 discussion for commercial stage of FCV and started DIS ballot from January 2011.
ISO/TC22/SC21 (electric vehicle): JARI continued discussion of safety and fuel consumption of FCV and contributed on revision of IS23273-3.
