Parameter extraction of fuel cells using hybrid interior search algorithm

Summary Precise modelling of fuel cells is very important for understanding their functioning. In this work, an application of hybrid interior search algorithm (HISA) is proposed to extract the parameters of fuel cells for their electromechanical equations based on nonlinear current‐voltage characteristics. Proposed hybridised algorithm has been developed using evolutionary mutation and crossover operators so as to enhance the modelling capability of interior search algorithm (ISA). To assess the modelling performance of HISA, parameter extraction of two types of fuel cell models, namely, proton exchange membrane fuel cell (PEMFC) and solid oxide fuel cell (SOFC) have been considered. Modelling performance of HISA, assessed using mean squared error between computed and experimental data, is found to be superior to ISA and several other recently reported prominent optimisation methods. Based on the presented intensive simulation investigations, it is concluded that HISA improves the performance of the basic ISA in terms of fitter solutions, robustness, and convergence rate and therefore offers a promising optimisation technique for parameter extraction of fuel cells.

“…The Solid Oxide Fuel Cell (SOFC) is the type of fuel cell where the electrolyte is composed of a ceramic material. Due to their high efficiency, high quality waste heat and ability to use a wide variety of fuels, SOFCs are a promising technology proposed for distributed power generation, the reduction of pollution and decreasing fossil fuel consumption [1,2]. An SOFC electrode is made of ceramic-metal composite characterized by a complex multi-phase microstructure.…”

A Three-Dimensional Numerical Assessment of Heterogeneity Impact on a Solid Oxide Fuel Cell’s Anode Performance

et al. 2018

View full text Add to dashboard Cite

In this research, a fully three-dimensional, multiphase, microstructure-scale heterogeneous (non-continuous) electrode, Solid Oxide Fuel Cell (SOFC) stack model is implemented in order to assess the impact of homogeneity disturbance in an SOFC anode. The Butler–Volmer model is combined with recent empirical relations for conductivity and aspects of the Maxwell–Boltzmann kinetic theory describing the transport of mass within the porous medium. Methods for the localized quantification of electrode morphology parameters (such as triple phase boundary length) are implemented. The exchange current distribution in the electrode, the partial pressures and the electric potential fields for each phase are computed numerically. In order to simulate heterogeneity, transfer barriers of varying placement and size are added to an otherwise homogeneous, virtual microstructure based on data from FIB-SEM tomography. The results are compared to a model based on the continuous electrode theory, and the points of discrepancy are highlighted.

“…High temperature fuel cells emerge as a promising energy approach for stationary systems of power generation from unconventional sources . Molten carbonate fuel cells (MCFCs) and solid oxide fuel cells (SOFCs) are attractive for the power market, particularly in the field of distributed generation of clean electricity . Their high operation temperatures, that is, 650–1000 °C, offer to achieve high power density and efficiency, however, also cause challenges to catalysts, mainly in terms of their stability during long term operation …”

Characterization of Spatial Distribution of Electrolyte in Molten Carbonate Fuel Cell Cathodes

et al. 2018

View full text Add to dashboard Cite

High-resolution computed X-ray tomography (XCT) is applied in this study to characterize the microstructure of Molten Carbonate Fuel Cell (MCFC) cathodes after operation, where a "virgin cathode" formed by porous nickel has been in situ oxidized and infiltrated by liquid electrolyte. This technique extends state-of-the art methodology to characterize pores such as porosity analysis using Mercury porosimetry. XCT enables 3D imaging of the internal structure of the electrodes including all components present at the cathode side, particularly NiO, pores, and electrolyte. The quantitative 3D microstructure analysis based on high-resolution XCT provides topological information for each component and their mutual spatial distribution, which is significant for the enhancement of the MCFC performance. In particular, volume fraction, specific surface area, continuity of each phase, as well as the Triple Phase Boundary (TPB) density are calculated from the experimental data. The results indicate that superior properties of the multi-modal pore sized cathode, used in this study, can be attributed to the formation of three selfinterpenetrating networks of pathways for the transport of gasses, electrons, as well as ions throughout pores, NiO, and electrolyte, respectively.
