SOFC Modeling - From Micro-Kinetics to Stacks
This paper presents a hierarchical modeling approach for Solid-Oxide Fuel Cells from elementary kinetics to stacks. On a fundamental level, we have developed an analytical model for the evaluation of volume specific three-phase boundary length (vLtpb) in composite electrodes and electrochemical kinetics expressions to account for coverage dependent activation energies of various surface adsorbe...
متن کاملSorting with Complete Networks of Stacks
Knuth introduced the problem of sorting with a sequence of stacks. Tarjan extended this idea to sorting with acyclic networks of stacks (and queues), where items to be sorted move from a source through the network to a sink while they may be stored temporarily at nodes (the stacks). Both characterized which permutations are sortable; but complexity of sorting was not an issue. In contrast, give...
متن کاملDynamic Analysis of Load Operations of Two-Stage SOFC Stacks Power Generation System
The main purpose of this paper was to develop a complete dynamic model of a power generation system based on two serially connected solid oxide fuel cell stacks. The uniqueness of this study lies in a different number of fuel cells in the stacks. The model consists of the electrochemical model, mass and energy balance equations implemented in MATLAB Simulink environment. Particular attention ha...
متن کاملModeling Interferogram Stacks for Sentinel - 1
The dispersion of the optimal estimate of a subsidence motion is determined, and compared with that of Permanent Scatterers, when the targets are progressively decorrelating due to Brownian motion. Approximately, with N consecutive images and revisit time T, the interferogram stack results are equivalent to PS's, if the pixel count in the window grows with N2T, independently of the frequency. I...
متن کاملPerformance modeling and parametric investigation of a solid oxide fuel cell (SOFC)
In his paper, performance modeling and parametric study of a tubular solid oxide fuel cell (SOFC) fed by hydrogen was conducted. The components of the fuel cell system and its reactions were entirely modelled and an electrochemical analysis done for it. A variety of modeling parameters including temperature, working pressure and the air mass- flow rate have been investigated in order to observe...
