  1. Activities of JBRCwithin the FP6 EU IP Roads2HyCOMJan Macek, Jiří VávraJosef Božek Research Center, Czech Technical University in Prague Meeting with the Czech Hydrogen Platform

  2. Contents • Education Agenda for MechEng • Simple Tank-to-Wheels Analysis Tool for Future Vehicle Powertrains Meeting with the Czech Hydrogen Platform

  3. Levels of Academic Agenda How to Do It – Modular structure is suitable for other stakeholder information The goals of the academic agenda may be covered by module curricula at different levels with different pre-requisites. The lower level courses use the simplified modules of higher level ones. Master of Science in Hydrogen Engineering (4 semesters) Bachelor of Hydrogen Technologies Implementation (2 semesters) Life-long training courses for graduated engineers • full semester training (50 days) • short (weekend) training (10 days) Requirements Summer schools and workshops for graduated engineers (1 week) The simplified modules may be applied for other education aims. Meeting with the Czech Hydrogen Platform

  4. Contents • Education Agenda for MechEng • Simple Tank-to-Wheels Analysis Tool for Future Vehicle Powertrains Meeting with the Czech Hydrogen Platform

  5. Introduction • Aim of the Study • Assessment of potential of future vehicle powertrains especially fuel cell (FC) based in comparison to an internal combustion engine (ICE) as a vehicle prime mover • Transparent, reasonably simplified software tool for assessment of efficiency potential been developed within the WP4, Task 4.4 • for various types of vehicle powertrains • FC, ICE, Hybrid • various types of vehicles (car, light truck, city bus) • arbitrary driving cycle • NEDC Meeting with the Czech Hydrogen Platform

  6. Methodology Coverage of all driving resistances by a prime-mover taking into account: • prime mover efficiency • ICE performance maps • PEM FC incl. auxiliaries • transmission efficiency • CVT – optimum efficiency line • electric drive efficiency: • Quasi-static features of powertrains Impact of the vehicle weight (H2 FC, Hybrid) TTU instead of TTW Meeting with the Czech Hydrogen Platform

  7. Strategies compared Main parameters of a car used in model SI ICE CI ICE H2 ICE PEMFC CI ICE Hybrid Meeting with the Czech Hydrogen Platform

  8. Optimal fuel consumption line evaluation Meeting with the Czech Hydrogen Platform

  9. Fuel Cell Performance Characteristics Meeting with the Czech Hydrogen Platform

  10. Comparison of optimal lines of specific heat consumption of ICEs and H2 FCs Meeting with the Czech Hydrogen Platform

  11. NEDC Results Meeting with the Czech Hydrogen Platform

  12. Future Development of the Simulation Tool • The corrections for transient response will be implemented to the simulation. • Their estimate depends on the SOTA of detailed dynamic simulation • At present mastered for ICE only • Next development steps - Diploma Projects • combination of FC and electric accumulator • load of fuel cell in real hybrid will be significantly higher due to the need for recharging an accumulator or a supercapacitor • The FC efficiency will be then lower depending on average power demand, especially high for motorway operation (FC characteristics at higher loads) Meeting with the Czech Hydrogen Platform

  13. Thank you for your attention!!!27th and 28th November 2008 General Assembly in Prague Meeting with the Czech Hydrogen Platform
