This thesis presents the development, construction, and benchmark of an experimental platform that combines cold fermionic 6Li atoms with locally controllable light-matter interactions. To enable local control, a new device, the cavity-microscope, was crea ...
Hydrogen fuel cells are an essential component of hydrogen economy, which have been advocated as a major path towards the decarbonization of the energy sector. Within the two main types of low-temperature hydrogen fuel cells, anion-exchange membrane fuel c ...
Hydrogen powered vehicles use high-pressure reservoirs from which the gas is transferred to the low-pressure fuel-cell via a classical pressure reduction valve. In these systems no expansion work is recovered and the question is addressed of the potential ...
Hydrogen storage and utilization are the technologies to achieve carbon-neutral energy systems with renewable energy sources. Among the various materials that have been investigated, complex hydrides are a material exhibiting high gravimetric hydrogen dens ...
The current study performs the thermodynamic and life-cycle assessments (LCA) of a novel charging station in two system designs. The goal is to design an efficient charging station for electric vehicles with high efficiencies and low environmental impacts ...
The current study evaluates integrating fuel cell technology into the batteries as an alternative for internal combustion engines (ICEs) for Unmanned Aerial Vehicles (UAV). To further improve the performance of the UAV, a turbocharger is also integrated to ...
Anion exchange membrane fuel cells (AEMFCs) are considered one of the most promising and efficient hydrogen conversion technologies due to their ability to use cost-effective materials. However, AEMFCs are still in an early stage of development and the lac ...
The depletion of fossil fuel sources has encouraged the authorities to use renewable resources such as wind energy to generate electricity. A backup/storage system can improve the performance of wind turbines, due to fluctuations in power demand. The novel ...
A strategic roadmap for noncarbonized fuels is a global priority, and the reduction of carbon dioxide emissions is a key focus of the Paris Agreement to mitigate the effects of rising temperatures. In this context, hydrogen is a promising noncarbonized fue ...
Catalyst layers in proton exchange membrane fuel cells consist of platinum-group-metal nanocatalysts supported on carbon aggregates, forming a porous structure through which an ionomer network percolates. The local structural character of these heterogeneo ...
