Design and optimisation of a multi-stack reversible PEM fuel-cell system for automotive mobility. Emphasis on hydrogen energy management, efficiency and bidirectional operation. Experimental validation using multi-stack configuration and controlled load conditions. Demonstrates scalable behaviour relevant to future hydrogen-powered vehicles.

This work investigated the effect of selective laser melting processing conditions on the microstructure and mechanical behaviour of Al2139 aluminium alloy. Optical microscopy, SEM analysis and mechanical testing were used to link the processing conditions to the density, hardness and corrosion performance for structural applications of additive-manufactured parts.
