1. On direct hydrogen fuel cell vehicles : modelling and demonstration
Sammanfattning : In this thesis, direct hydrogen Proton Exchange Membrane (PEM) fuel cell systems in vehicles are investigated through modelling, field tests and public acceptance surveys. A computer model of a 50 kW PEM fuel cell system was developed. The fuel cell system efficiency is approximately 50% between 10 and 45% of the rated power. LÄS MER
2. Towards sustainable urban transportation : Test, demonstration and development of fuel cell and hybrid-electric buses
Sammanfattning : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. LÄS MER
3. On Hybrid Fuel Cell and Battery Systems for Maritime Applications
Sammanfattning : Hydrogen is seen as a key player in leading to a sustainable energy sector and decarbonizing the transport sector. Proton Exchange Membrane Fuel Cells (PEMFCs) consume hydrogen and oxygen to generate water, heat and electricity. LÄS MER
4. A Methodology for the Design of Cost Effective Hybrid Vehicles
Sammanfattning : This thesis deals with system design of cost effective hybrid and fuel cell vehicles. Today (2004) the major disadvantages of these vehicles are increased complexity and component costs. However, the decrease in cost of electrical components and the environmental concern make these vehicles more and more competitive. LÄS MER
