- W4327595265 abstract "Hydrogen fuel cells are a potential route to decarbonize the automotive sector due to the zero CO2 tailpipe emissions, faster re-fuelling, and higher energy density than their direct competitor, the battery-electric powertrain. One of the key challenges is to find the best air path configuration to achieve high efficiency in a system level. This work aims to optimize, setup, and demonstrate a highly efficient Proton Exchange Membrane fuel cell system (PEMFC). This powerplant is hydrogen fuelled and scalable to achieve the required power output for different vehicles. This work evaluates a PEMFC by a 1D-numerical approach. The fuel cell is modelled, validated, and later studied under different air inlet conditions. The main goal is the evaluation of different air path layouts to achieve the highest system efficiency. Numerical simulations of electric compressor and coupled and de-coupled electrically assisted turbocharging are performed with different component sizes and cathode pressures. Therefore, this work provides an overview of our initial findings that will outline the key modelling challenges for fuel cell systems and then present a comparison of different air-path architectures. The coupled electrically assisted turbocharger is determined to be the best layout with an improvement of 10% of the delivered power at a high current load. The e-turbocharging optimized by the proposed methodology allows reduction of the peak electric machine electric power by 60%." @default.
