Solid Oxide Fuel Cells - The University of Nottingham.

ABSTRACT In this thesis, several models of solid oxide fuel cell (SOFCs) were developed in cell and system levels. These modelswere used in several case studiesto simulate the performance of the cells and systems studied. In addition, the effectiveness of SOFC in reducing greenhouse gases was assessed through a case study.

This PhD thesis presents a modelling and simulation approach for coupling a Solid Oxide Fuel Cell (SOFC) with a Vapour Absorption Refrigeration System (VARS) specifically for refrigerated trucks. Zero dimensional models were developed for the SOFC and VARS and detailed 1D and 3D models were developed for various components of the system.

Theoretical and Experimental Study of Solid Oxide Fuel.

In this thesis, fuel cell systems are analysed thermodynamically and electrochemically. Thermodynamic relations are applied in order to determine the change of first law and second law efficiencies of the cells, and using the electrochemical relations, the irreversibilities occuring inside the cell are investigated.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.An innovative current collection architecture for micro-tubular solid oxide fuel cells (SOFC) has been developed. A nickel wire is coiled around a thin carbon composite rod in order to fabricate cell supports. Different carbon composites such as pencil leads and carbon fibres were investigated.


A solid oxide fuel cell (or SOFC) is an electrochemical conversion device that produces electricity directly from oxidizing a fuel. Fuel cells are characterized by their electrolyte material; the SOFC has a solid oxide or ceramic electrolyte.This thesis presents the results of a computational study of bulk SmCoO 3 -based perovskites for use as Intermediate Temperature Solid Oxide Fuel Cell (IT-SOFC) cathode.

Solid oxide fuel cells represent an energy conversion device with high efficiency and fuel versatility but continue to suffer from cost and durability issues, hindering commercial viability.

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.
