11. Design and evaluation of stationary polymer electrolyte fuel cell systems
Sammanfattning : The objectives of this doctoral thesis are to give a basisincluding methods for the development of stationary polymerelectrolyte fuel cell (PEFC) systems for combined heat andpower production. Moreover, the objectives include identifyingprerequisites, requirements and possibilities for PEFC systemsproducing heat and power for buildings in Sweden. LÄS MER
12. Dynamic regulation of DNA methylation in human T-cell biology
Sammanfattning : T helper cells play a central role in orchestrating immune responses in humans. Upon encountering a foreign antigen, T helper cells are activated followed by a differentiation process where the cells are specialised to help combating the infection. LÄS MER
13. Nanostructured Model Electrodes for Studies of Fuel Cell Reactions
Sammanfattning : There is currently a general need for alternative and sustainable energy systems. As part of such a system, the polymer electrolyte fuel cell (PEMFC) offers efficient and emission free energy conversion. LÄS MER

15. Evaluating Cathode Catalysts in the Polymer Electrolyte Fuel Cell
Sammanfattning : The polymer electrolyte membrane fuel cell (PEMFC) converts the chemical energy of hydrogen and oxygen (air) into usable electrical energy. At the cathode (the positive electrode), a considerable amount of platinum is generally required to catalyse the sluggish oxygen reduction reaction (ORR). LÄS MER
