Pressurized Solid Oxide Fuel Cells with Reformate as Fuel

In this contribution the influence of pressure on an SOFC is studied with steam-reformed methane as a fuel. Experiments were performed with a reformate containing 58.4% H2, 20% H2O, 12.2% CO, 5.5% CO2 and 3.9% CH4 and another mixture containing 18% H2, 34% H2O, 2% CO, 27% CO2 and 19% CH4 as well as...

Zusammenfassung:In this contribution the influence of pressure on an SOFC is studied with steam-reformed methane as a fuel. Experiments were performed with a reformate containing 58.4% H2, 20% H2O, 12.2% CO, 5.5% CO2 and 3.9% CH4 and another mixture containing 18% H2, 34% H2O, 2% CO, 27% CO2 and 19% CH4 as well as a hydrogen/nitrogen mixture. The influence of pressure on OCV, power density at constant voltage and constant current as well as on gas composition was examined for the different fuels. Power density increases of up to 70% were found.
