12. NEXT STEP: Improving FC Vehicles (2006-2010)
CRF Research Activities are addressing the following priorities:
Fuel Cell tecnologies for improved efficiency (>50%), extended performances
(-30°C--+50°C ambient, 5000 hrs duration) and lower Cost:
- New hydrogen recirculation circuits
- Simplified humidification techniques
- High temperature membrane (>90°C)
- Cooling circuit and materials for low temperature operation (-30°C)
- On board diagnosis for enhanced Safety
- New generation, high-voltage low-cost Stacks with simplified design,
improved catalytic materials and automated assembly
Standardisation of Components and subsystems for applications both to Cars and Buses.

HYDROGEN SAFETY

14. Hydrogen Vehicles Safety User Expectations for Hydrogen Vehicles :
No additional tasks or responsibility during vehicle lifecycle, e.g. refuelling or maintenance
No additional costs, including maintenance and repair
Safety levels equal or better of current vehicles

15. Priority Investigation Areas
HYDROGEN VEHICLES
Safety
Priority Investigation Areas
H2 Leakage Detection and Recovery during Vehicle Refuelling, Stationary and Dynamic Operation.
Improved high pressure H2 Storage; integrity status & performance monitoring.
Crashworthiness of hydrogen components
Automated Emergency interventions, e.g. Hydrogen discharge in case of crash, fire-explosion risk
Passive mitigation engineering measures to protect occupants and surroundings from disruptive events
such as explosion and fire
Other Issues
Electrical shock prevention.
The Approach includes the development of comprehensive sensing,diagnostics and control technologies, the adoption of engineering based on best practices and consistent experimental data base, exhaustive test and analysis procedures.
SOLUTIONS MUST BE RELIABLE, SIMPLE AND COST EFFECTIVE
to increase public confidence on Hydrogen safety and reliability
“better than current vehicles”
