Pore-scale investigation of water-gas transport in reconstructed gas diffusion layers with binder and polytetrafluoroethylene coating Open
The microstructure of the gas diffusion layer (GDL) influences the fuel cell performance significantly. A deeper understanding of the transport processes within the GDL is crucial for its optimisation. In this study, a porous microstructur…

Experimentally validated performance improvements of a cathode air supply for PEM fuel cells Open
The air supply system of a PEM fuel cell usually consists of a centrifugal compressor as the core component. The operating range of turbomachines is generally limited, reducing the operational flexibility of the fuel cell. In order to supp…

Novel anode recirculation blower for PEM fuel cells Open
A novel anode recirculation blower for PEM fuel cell is developed and tested experimentally with different gas mixtures. The blower is based on a centrifugal turbocompressor driven by a specific electric motor, the Media Gap Motor. This mo…

Design and validation of a pulse generator for the pulse shaping of the turbine inlet pressure at the hot-gas test bench Open
In order to reproduce the unsteady turbocharger-turbine inlet conditions generated by an engine at a hot-gas test bench, a novel pulse generator unit (PGU) has been developed. This PGU modulates pressure-oscillations to the turbocharger in…
