PhD Theses
Abstract. Solid oxide fuel cell (SOFC) is a promising alternative energy source, with its advantages of high operating efficiency, fuel flexibility, low emissions and relatively low cost. However, there are several challenges concerning the SOFC research. Little is known about the complex interfacial electrochemistry and thermochemistry, and it · This PhD thesis targets the development of a computational methodology to predict and optimize the impact of manufacturing parameters on the architectural and electrochemical properties of solid oxide cells for electrolysis production of hydrogen and The goal of this thesis was to investigate the effects of hydrogen recirculation in a polymer electrolyte membrane fuel cell (PEMFC) on hydrogen stoichiometry and on the build-up of nitrogen in the recirculated stream as well as the effects of
Skills/Qualifications
· PhD thesis, University of Sheffield. Abstract Proton Exchange Membrane (PEM) fuel cells have a great potential to replace conventional fossil fuel dependent power conversion technologies in a wide range of portable, automotive and stationary applications and this is due to their high efficiency, quick start-up and sizing blogger.com: Raja Arif, Raja Muhammad Aslam Hydrogen proton exchange membrane fuel cells (PEMFCs) are a key technology in enabling the transition to net-zero carbon energy. Hydrogen powered fuel cell stacks have been demonstrated to be eminently suitable for powering cars and especially trucks, because battery solutions are not viable for most larger vehicles One of the major goals of this research was to investigate ion transport within the catalyst layer of fuel cell electrodes and attempt to improve it. -- One method used to study ion transport within fuel cell electrodes was to incorporate electroactive metal complexes into the catalyst layer to act as a probe. It was found that a lower fraction of the complexes were electrochemically active in

The primary focus of this thesis is on cancer cells of different invasive potential, and char-acterization of inherent properties that differ between non-invasive and invasive strains of similar origin. To understand our motivation we will outline some of the main aspects of cancer cells, especially in respect to their survival and spreading In this thesis, a computational framework for fuel cell analysis and optimization is presented as an innovative alternative to the time consuming trial-and-error process currently used for fuel cell design. The framework is based on a two-dimensional through-the-channel isothermal, isobaric and single phase membrane electrode assembly (MEA) model Abstract.
