ICHS: International Conference on Hydrogen Safety, 8th September, 2005, Pisa, Italy The New Facility for Hydrogen and Fuel Cell Vehicle Safety Evaluation Japan Automobile Research Institute S.Watanabe, Y.Tamura, J.Suzuki
Approach to Hydrogen Society 【R&D of H2&FC Technology】 ・Fundamental Research and Breakthrough Technology for Fuel Cell Vehicle and Hydrogen Infrastructure 【Demonstration & Promotion】 ・FCV Introduction by the Government ・Financial Support for FCV Introduction ・Hydrogen Infrastructure Promotion 【Establishment of Social Institutions】 ・Regulations, Codes & Standards for FCVs
Safety Issues of H2 FCVs 【Peculiar to H2 FCVs】 Hydrogen Safety ・High Pressure Cylinder & Vehicle ・Leakage and Ignition of Hydrogen ・Fire Fighting & Rescue at the accident 【Same as Conventional Vehicles】 Crash Safety High Voltage Safety Electromagnetic Compatibility (EMC)
Vehicle Fire Test CNG(20MPa, Two 34L Tanks) Gasoline(40L in a Steel Tank) H2 Upward(35MPa, Two 34L Tanks) H2 Downward(35MPa, Two 34 L Tanks)
Vehicle Fire Test CNG(20MPa, Two 34L Tanks) Gasoline(40L in a Steel Tank) H2 Upward(35MPa, Two 34L Tanks) H2 Downward(35MPa, Two 34 L Tanks)
Heat Irradiation Comparison Gasoline Vehicle intermittent large flame, long duration CNG Vehicle (Downward) large flame area, highest irradiation peak longer duration than hydrogen H2 Vehicle (Upward) no measurable irradiation peak H2 Vehicle (Downward) short duration
Subjects of Hydrogen Fire Safety Test Higher Pressure: 35MPa to 70MPa Larger Capacity: Passenger Car to Bus Application Tank Number: Single Tank System, Multi-tank System Storage Technologies Liquefied Hydrogen Tank Combination of Metal Hydride and High Pressure Tank Chemical Hydrides Carbon Adsorption etc. Comprehensive Hydrogen Safety Evaluation Facility
Hy-SEFHydrogen and Fuel Cell Vehicle Safety Evaluation Facility
Explosion Resistant Fire Test Cell Silencer Air Supply Blower Exhaust Emissions After Treatment Equipment Exhaust Blower Internal Structure of Fire Test Cell External Appearance of the Facility
Specification of Fire Test Cell Inside Dimensions: 16m Height, 18m Diameter, Enough Space to Observe the Flame Propagation Area Wall Thickness: 1.2m Wall, 1.4m Ceiling, 4.0m Ground Floor Enough Strength Against Possible Explosions Suppose the Explosion of 260 liter and 70MPa Tank Air Supply and Exhaust Blower: 750 m3/min. Enough Air Supply to Maintain a Vehicle Fire Exhaust Gas After Treatment: Ceramic Filter and Dry Adsorption by a Mixed Agent (Diatomite, Hydrated Lime, Activated Charcoal) Clean Exhaust Emission without Smoke or Harmful Substances Silencer: Reducing the Noise Level by 80 dB
The Advantages of Indoor Test Facility 1.The repeatability of the tests. Not depending on the climate ( wind, rain, snow etc.) 2.Easy to provide the high technology measurement equipments 3.Environmental friendly. Doesn’t emits sound, smoke, broken parts to the outside. 4.Comfortable for the workers.
Bonfire Test of Hydrogen Tank In every test, PRD was operated and no explosion, no blow-off was occurred.
