Modeling solid oxide fuel cells using continuous-time recurrent fuzzy systems

Modeling of Solid Oxide Fuel Cells

A comprehensive membrane-electrode assembly (MEA) model of Solid Oxide Fuel Cell (SOFC)s is developed to investigate the effect of various design and operating conditions on the cell performance and to examine the underlying mechanisms that govern their performance. We review and compare the current modeling methodologies, and develop an one-dimensional MEA model based on a comprehensive approa...

Modeling of Solid-Oxide Fuel Cells

This article presents a brief review on modeling philosophies of solid-oxide fuel cells (SOFCs) including an introduction to SOFC components and their functions. While a plethora of numerical models is available for SOFC modeling and simulation, this paper focuses on a general overview on mathematical model equations that represent the physico-chemical processes occurring in SOFCs and their bou...

Modellierung dynamischer Systeme mit zeitkontinuierlichen rekurrenten Fuzzy-Systemen (Modeling of Dynamical Systems Using Continuous-time Recurrent Fuzzy Systems)

In diesem Beitrag wird die Anwendung zeitkontinuierlicher rekurrenter Fuzzy-Systeme (KRFS) zur Modellbildung technischer Systeme beschrieben. Ausgehend von der Systembeschreibung rekurrenter Fuzzy-Systeme werden Verfahren vorgestellt, mit denen das KRFS das Verhalten des Prozesses anhand von Messdaten und qualitativem Prozesswissen erlernen kann. Die Leistungsfähigkeit wird anhand der Modellier...

Importance of Anode Microstructure in Modeling Solid Oxide Fuel Cells

A one-dimensional button-cell model is developed and applied to explore the influence of anode microstructure on solid oxide fuel cell (SOFC) performance. The model couples porous-media gas transport and elementary electrochemical kinetics within a porous Ni-YSZ cermet anode, a dense YSZ electrolyte membrane and a composite LSM-YSZ cathode. In all cases the fuel is humidified H2 and air is the ...
