Recent interest in fuel cell-gas turbine hybrid applications for the aerospace industry has led to the need for accurate computer simulation models to aid in system design and performance evaluation. To meet this requirement, solid oxide fuel cell (SOFC) and fuel processor models have been developed and incorporated into the Numerical Propulsion Systems Simulation (NPSS) software package. The S...

This paper presents a hydrogen powered hybrid solid oxide fuel cell-steam turbine (SOFC-ST) system and studies its optimal operating conditions. This type of installation can be very appropriate to complement the intermittent generation of renewable energies, such as wind generation. A dynamic model of an alternative hybrid SOFC-ST configuration that is especially suited to work with hydrogen i...

The idea of a fuel cell was first discovered in 1839 by Christian Friedrich Schönbein [64] and William Grove [27]. Independently from each other they provided the foundation for the development of many different kinds of fuel cells. Today’s fuel cells are mostly classified by the type of electrolyte used in the cells. The most common types are polymer electrolyte fuel cells PEFC (developed by W...

Designing optimal microstructures for solid oxide fuel cell (SOFC) electrodes is complicated due to the multitude of electro-chemo-physical phenomena taking place simultaneously that directly affect working conditions of a SOFC electrode and its performance. In this study, a new design paradigm is presented to obtain a balance between electrochemical sites in the form of triple phase boundary (...

Steel interconnect robustness under SOFC conditions for extended operation remains a challenge. The observation and analysis of the microstructure aged in real long periods provides data to help understand degradation potentially design accelerated testing.In this study, TEM observations cross section interconnects (9000h 20000h stacks) are presented. Crofer22APU with air side coated manganese ...

In the era of gigascale integration, both interconnect technologist and interconnect circuit designers must work together closely to ensure that the integrated circuit (IC) industry will overcome current and future interconnect limits on system performance, power dissipation, noise, and cost. This paper will review wave-pipelined interconnect circuits that are used to enhance wire performance a...

Development of solid oxide fuel cell (SOFC) anode with high resistance to coking and sulfur poisoning is highly desirable for the direct application natural gas in SOFC. Herein, a (Cu, Sm)CeO2 anchored Cu nanoparticles has been prepared. Most particle size ranges from 20 50 nm, which can increase conductivity catalytic activity anode. The Cu/CSCO10 supported exhibits maximum power density 404.6...

Direct internal reforming in solid oxide fuel cell (SOFC) results in increased overall efficiency of the system. Present study focus on the chemical and electrochemical process in an internally reforming anode supported SOFC button cell running on humidified CH4 (3% H2O). The computational approach employs a detailed multi-step model for heterogeneous chemistry in the anode, modified Butler–Vol...
