1. The anode in a PEFC reformate system
Sammanfattning : Polymer electrolyte fuel cells (PEFC) constitute one ofseveral types of fuel cells that can be used to converthydrogen to electricity and heat. PEFC co-generation systemsbased on fossil fuels are on the edge of commercialisation.Biogas may be a future fuel in these kinds of systems. LÄS MER
2. The Anode in the Direct Methanol Fuel Cell
Sammanfattning : The direct methanol fuel cell (DMFC) is a very promisingpower source for low power applications. High power and energydensity, low emissions, operation at or near ambientconditions, fast and convenient refuelling and a potentiallyrenewable fuel source are some of the features that makes thefuel cell very promising.

3. Durability of Reinforced Concrete under Impressed Current Cathodic Protection
Sammanfattning : Impressed current cathodic protection (ICCP) and prevention (ICCPre) are reliable and efficient techniques to stop, control and postpone corrosion in reinforced concrete structures. However, the wide application of this technique has been limited by the high cost of the anode system. LÄS MER
4. XPS studies of an organic anode and hole-conductor system : PEDOT-PSS
Sammanfattning : This thesis deals with photoelectron spectroscopy of conducting polymer systems. A particular system, poly(3,4-ethylenedioxythiophene) polystyrenesulfonic acid (PEDOT-PSS), has been the main focus of this work. It is an aqueous colloidal dispersion consisting of doped conjugated polymer PEDOT with counter ions provided by the PSS chains. LÄS MER
5. Design and Characterisation of new Anode Materials for Lithium-Ion Batteries
Sammanfattning : Reliable ways of storing energy are crucial to support our modern way of life; lithium-ion batteries provide an attractive solution. The constant demand for higher energy density, thinner, lighter and even more mechanically flexible batteries has motivated research into new battery materials. Some of these will be explored in this thesis. LÄS MER
