1. Bringing fuel cells to reality and reality to fuel cells A systems perspective on the use of fuel cellsDetta är en avhandling från Stockholm : KTH
Sammanfattning : With growing awareness of global warming and fear of political instability caused by oil depletion, the need for a society with a sustainable energy system has been brought to the fore. A promising technology often mentioned as a key component in such a system is the fuel cell technology, i.e. LÄS MER
- Detta är en avhandling från Stockholm : KTH
Sammanfattning : This thesis concerns biogas-operated fuel cells. Fuel cell technology may contribute to more efficient energy use, reduce emissions and also perhaps revolutionize current energy systems. The technology is, however, still immature and has not yet been implemented as dominant in any application or niche market. LÄS MER
3. Modelling of Solid Oxide Fuel Cells Applied to the Analysis of Integrated Systems with Gas TurbinesDetta är en avhandling från Department of Heat and Power Engineering, Lund university
Sammanfattning : Solid oxide fuel cells (SOFCs), working at high temperatures with an incomplete fuel oxidation process, have become an interesting candidate for combination with conventional power generation technology, such as gas turbines, in order to develop power plants that are both functional and efficient. An absolute condition for successful analysis and optimisation of such plants is the existence of reliable simulation tools. LÄS MER

Sammanfattning : Hydrogen technologies are rapidly receiving increased attention as it offers a renewable energy alternative to the current petroleum-based fuel infrastructure, considering that continued large-scale use of such fossil fuels will lead to disastrous impacts on our environment. The proton exchange membrane fuel cell should play a significant role in a hydrogen economy since it enables convenient and direct conversion of hydrogen into electricity, thus allowing the use of hydrogen in applications particularly suited for the transportation industry.

- Detta är en avhandling från Stockholm : KTH Royal Institute of Technology
Sammanfattning : Molten Carbonate Fuel cells are high temperature fuel cells suitable for distributed generation and combined heat and power, and are today being installed on commercial basis in sizes from 100kW to several MW. Novel applications for MCFC which have attracted interest lately are MCFC used for CO2 separation from combustion flue gas, and high temperature electrolysis with reversible fuel cells. LÄS MER
