Wärmehaushalt einer Karbonat-Brennstoffzelle zur Wasserstoffherstellung für eine Polymerelektrolyt-Brennstoffzelle
Molten carbonate fuel cells (MCFC) are being used in decentralised power plants, as they can reform hydrocarbon bound fuels internally, e.g. netural gas with a energy density of 10 kWh/m3 at standard conditions, and the efficiency of this mode of operation is around 50%. However in comparison to …

Massenströme und Stromdichteverteilung in flüssig gespeisten Direkt-Methanol-Brennstoffzellen
The present study is concerned with the process-related and fluid dynamic analysis of liquid feed Direct-Methanol-Fuel-Cells (DMFC). The influence of operating and design parameters on the performance and the mass and heat balance is investigated. For this purpose experimental studies and modelling …

Stromdichten in Rezeptoren-Bereichen bei Sinneswahrnehmungen in niederfrequenten elektromagnetischen Feldern
Low-frequency electromagnetic fields, as they are emitted by facilities of electrical energy supply, can cause so-called non-adequate stimuli in the human organism, if they reach sufficient strength. These non-adequate stimuli can feign or mask adequate stimuli, which are caused by signals from the …
