Sheikhansari, Abdolkarim (2017) Evaluation of Solid Oxide Fuel Cells Operating on Hydrogen Sulfide Contaminated Fuel. PhD thesis, University of Sheffield.
Chapter 1 gives a short introduction to fuel cells including the electrochemical principles and the conventional and state-of-the-art materials of Solid Oxide Fuel Cells (SOFC). It also presents the motivation and objectives of the thesis.
Optimisation of Electroless Co-deposited Solid Oxide Fuel Cell Electrodes by Nkem O.E. Nwosu (B.Sc, M.Sc) A thesis submitted in partial fulfilment of the requirements of Edinburgh Napier University, for the award of Doctor of Philosophy June 2013.
This thesis presents some model developments for the simulation and optimization of the design of fuel cells, in particular for the Solid Oxide Fuel Cell (SOFC) and Proton Exchange Membrane Fuel Cell (PEMFC). However, the approaches and models presented can be basically applied to any type of fuel cell. In this study, the multicomponent diffusion processes in the porous medium of a SOFC anode.
The objective of this dissertation is the development of new material combination for the fuel electrode with an improved tolerance against contaminants in the fuel gas.
Perovskite oxides have high catalytic activities for oxygen electrocatalysis competitive to platinum at elevated temperatures. However, little is known about the oxide surface chemistry that influences the activity near ambient oxygen partial pressures, which hampers the design of highly active catalysts for many clean-energy technologies such as solid oxide fuel cells.
