Verfahrenskonzepte für den Betrieb eines Direkt-Methanol-Brennstoffzellen-Systems

By R. Menzer, B. Höhlein and V. M. Schmidt

Abstract

There are two different procedures for using methanol as fuel in low-temperature fuel-cell systems. On the one hand, methanol can be reformed to a hydrogen-rich synthesis gas before the generation of electricity via an electrochemical reaction in a fuel cell; on the other hand, methanol can also be used directly for electricity generation inside the fuel Gell. This kind of direct methanol oxidation differs extremely from the indirect oxidation of methanol via hydrogen in terms of electrochemical basic reactions and process engineering units. This study includes the analyses of different concepts with liquid and gaseous methanol as energy input for fuel-cell systems. Based on simulation calculations, the operating requirements for specific procedures can be identified as a function of both operating conditions and the respective yield of electricity
