Master's thesis of Engineering: The feasibility of a unitised regenerative fuel cell with a reversible carbon-based hydrogen storage electrode

The specific objectives of this study are: 1. To conduct a literature review on carbon-based hydrogen storage electrodes and direct proton absorbance in various forms of carbon; 2. To prepare and characterise activated carbon samples with proper porosity for the present application; 3. To manufacture and characterise a range of composite materials containing carbon material and a proton-conducting medium such as nafion in various levels of hydration 4. To fabricate a number of membrane-electrode-assembly (MEA) from the composite materials;…

Metal composites behaviour under biaxial stresses

For this study, different volume fraction (vol.%) of particulate alumina (Al2O3) reinforced aluminium alloy (Al 6061) with 5 vol.%, 15 vol.% and 25 vol.% are produced by powder metallurgy method. These samples were subjected to biaxial stresses in order to investigate the behaviour of the metal matrix composites (MMCs). Microstructure analysis on the individual sample before and after loading was performed under scanning electron microscopy. The small particles of 2 µm in size have exhibited strong interfacial bonding with the matrix.
