Abstract [de]

Die Brennstoffzelle ist ein elektrochemischer Reaktor und wandelt chemisch gebundene Energie direkt in elektrische Energie um. In der stationären Energieerzeugung ist der Brennstoffzellenstapel selbst nur ein kleiner Bestandteil des vollständigen Systems. Die Integration aller zusätzlichen Bestandteile, der Peripheriegeräte (Balance-of-Plant) (BoP), ist eine der Hauptaufgaben in der Studie der Brennstoffzellenkraftwerke.

Diese Untersuchung betrifft die Systemstudie des auf der Schmelz-Karbonat-Brennstoffzelle (MCFC) basierten Kraftwerks. Die Systemstudie ist mit dem Simulationprogramm Aspen PlusTM durchgeführt worden.

Artikel I beschreibt die Implementierung eines in Aspen PlusTM entwickelten MCFC Stapelmodells, um ein MCFC Kraftwerk zu studieren, das Erdgas als Brennstoff verwendet.

Artikel II beschreibt, wie unterschiedliche Prozeßparameter, wie Brenngasnutzung und dieWahl des Brennstoffes, die Leistung eines MCFC Kraftwerks

Abstract [en]

A fuel cell is an electrochemical reactor, directly converting chemically bound energy to electrical energy. In stationary power production the fuel cell stack itself is only a small component of the whole system. The integration of all the auxiliary components, the Balance-of-Plant (BoP), is one of the main issues in the study of fuel cell power plants.

This thesis concerns the systems studies of molten carbonate fuel cell (MCFC) based power plants. The system studies has been performed with the simulation software Aspen PlusTM.

Paper I describes on the implementation of a developed MCFC stack model into Aspen PlusTM in order to study an MCFC power plant fueled with natural gas.

Paper II describes how different process parameters, such as fuel cell fuel utilization, influence the performance of an MCFC power plant.

Abstract [sv]

Bränslecellen är en elektrokemisk reaktor som kan direkt omvandla kemiskt bunden energi till elektrisk energi. I stationär kraftproduktion är själva bränslecellsstapeln endast en mindre komponent i systemet. Integrationen av kringutrustningen, den s.k. Balance-of-Plant (BoP), som tex. pumpar, kompressorer och värmeväxlare är en av huvudfrågeställningarna i studierna av bränslecellskraftverk. Denna avhandling avser systemstudier av mältkarbonatbränslecellsbaserade (MCFC) kraftverk. Systemstudierna har utförts med processimuleringprogramet Aspen PlusTM.

Artikel I beskriver en utvecklad MCFC-cellmodell, som implementeras som "user model" i Aspen Plus, för att studera ett naturgasbaserat bränslecellskraftverk.

Artikel II beskriver hur olika processparametrar, som tex bränsleutnyttjande och val av bränsle, påverkar ett MCFC-kraftverks prestanda.
