International Conference on Hydrogen SafetyRound Table Panel Discussion
Pisa, Italy
7 – 10 September 2005
Areas where standards for fuel cell vehicles differ from conventional
electric vehicles• fuel cell stack (electrical isolation) • fuel handling system (leak) • fuel storage system (unintended release) • refueling
Fuel CellPower Module
HydrogenStorage System
Hydrogen Fuel Handling System
vehicle-level crash performance standards
vehicle-level crash performance standards
system-level performance standards
interface-to-infrastructure prescriptive standards
* Fuel Cell = rechargeable (refuelable) battery
What do we want from Codes & Standards?
Public safety
Commercial feasibility• Infrastructure compatibility• International consistency
Rapid entry of new technology
Risk: premature & prescriptive standards slow advances
-- to be ready in the 2010 – 2015 timeframe
Solution: performance standards
Performance Standards
Require demonstration of safe performance under cumulative extremes of potential use
• same requirement regardless of materials used• same requirement regardless of method of construction• explicit linkage to extremes of potential use & exposure
Example: Vehicle Crash Test• vehicle hits barrier at specified speed & angle• required performance:
impact on passengers fuel release
design validation manufacturing validation
(periodic or batch test)
