1. Nanostructured Model Electrodes for Studies of Fuel Cell Reactions
Abstract : 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. READ MORE

2. Electrode Degradation in Polymer Electrolyte Fuel Cells
Abstract : To mitigate the climate crisis, and reduce carbon emissions from e.g. the transport and energy sectors, hydrogen has been proposed to be used as an environmentally friendly alternative energy carrier. READ MORE

3. Reactors and biosensors for improved microbial degradation of acetonitrile
Abstract : Biodegradation is becoming an attractive mode of operation for eliminating toxic chemicals released from industrial processes or already present in the environment. One needs, however, not only to identify organisms capable of degrading such chemicals, but also to address the issue of whether these chemicals, after being degraded, will be toxic to the degrading organisms if present in high concentrations.

4. Investigations of proton conducting polymers and gas diffusion electrodes in the polymer electrolyte fuel cell
Abstract : Polymer electrolyte fuel cells (PEFC) convert the chemically bound energy in a fuel, e.g. hydrogen, directly into electricity by an electrochemical process. Examples of future applications are energy conversion such as combined heat and power generation (CHP), zero emission vehicles (ZEV) and consumer electronics. READ MORE

5. Electrode degradation in proton exchange membrane fuel cells
Abstract : The topic of this thesis is the degradation of fuel cell electrodes in proton exchange membrane fuel cells (PEMFCs). In particular, the degradation associated with localized fuel starvation, which is often encountered during start-ups and shut-downs (SUs/SDs) of PEMFCs. At SU/SD, O2 and H2 usually coexist in the anode compartment. READ MORE
