This study has focused on solid oxide electrolyser cells for high temperature steam electrolysis. Solid oxide electrolysis is the reverse operation of solid oxide fuel cells (SOFC), so many of the same component materials may be used. However, other electrode materials are of in…
There is at present some uncertainty as to what the roles and requirements of the next generation of UAVs might be and the configurations that might be adopted. The incorporation of technological features on these designs is also a significant driving force in their configuratio…
The domestic sector will play an important role in the decarbonisation and decentralisation of the energy sector in the future. Installation numbers of building-integrated small-scale energy systems such as photovoltaics (PV), wind turbines and micro-combined heat and power (CHP…
The work in this thesis addresses the synthesis and characterization of porous carbon substrates, and their electrochemical and fuel cell evaluation. The approach involves using porous carbon materials of different pore characteristics as electrocatalyst materials for use as cat…
Perovskite structured oxides; La1-xSrxMnO 3-δ and LaxSr1-xCoyFe1-y O3-δ are widely used as cathode for oxygen reduction reaction in a solid oxide fuel cell (SOFC). To study the electrode mechanism, a model system was developed using dense thin-film electrodes. Polycrystalline na…
Of the fuel cells being studied, the proton exchange membrane fuel cell (PEMFC) is viewed as the most promising for transportation. Yet until today, the commercialization of the PEMFC has not been widespread in spite of its large expectation. Poor long term performances or durab…
This dissertation develops a systematic approach to comprehensively investigate the application potential of Solar PV, wind and fuel cells in reducing GHGs emissions for energy intensive global manufacturing industry. This systematic approach is developed by integrating the tech…
A complete system design and incorporation of a portable direct methanol fuel cell (DMFC) system is introduced. The different system hardware and the operational strategies, including a 16-bit microprocessor and electronics for actuators and sensors, is focused on robust operati…
Renewable energy is being increasingly deployed at both small and large scales. At large scale, the intermittent nature of renewable energy sources prohibits a full integration with the current power grid. Among others, redox flow battery is a promising energy storage technology…
