Modeling Of Proton Exchange Membrane Fuel Cell Systems

Publikation: Bog/antologi/afhandling/rapportPh.d.-afhandling

Abstrakt

The objective of this doctoral thesis was to develop reliable steady-state and transient component models suitable to asses-, develop- and optimize proton exchange membrane (PEM) fuel cell systems. Several components in PEM fuel cell systems were characterized and modeled. The developed component- and system models match experimental data from the literature. However, limited data were available for verification so further work is necessary to confirm detailed aspects of the models. It is nonetheless expected that the developed models will be useful for system modeling and optimization of PEM fuel cell systems. Consequences of indirectly fueling PEM stacks with hydrocarbons using reforming technology were investigated using a PEM stack model including CO poisoning kinetics and a transient Simulink steam reforming system model.
Aspects regarding the optimization of PEM fuel cell systems are discussed and heat integration of a steam reforming system using pinch technology and a simultaneous optimization approach solving a MINLP problem is described.
