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

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)
