A rigorous physics-based mathematical model for a solid oxide iron-air redox flow battery system is presented in this paper. The modeled flow battery system combines a Fe-FeO redox couple as the energy storage unit and a regenerative solid oxide fuel cell as the electrical functioning unit in a 2D axial symmetric geometry. This model was developed from fundamental theories of reaction engineering in which basic transport phenomena and chemical/electrochemical kinetics are included. The model shows good agreement with the experimental data. Simulation results for the chemical, electrochemical and transport behavior of the battery are discussed.

“…Besides that, the oxidation peak a 0 and the hydrogen evolution peak also occurs. The a 0 peak was ascribed to the oxidation of Fe to Fe(OH) ad before forming Fe(OH) 2 . Peak a 0 appears only with the addition of S 2-ion into electrolyte, thus the presence of K 2 S additive in electrolyte increases the reaction rate of Fe/Fe(I).…”

“…To meet the power requirements of these devices and vehicles, researches of batteries have been also constantly evolved. In recent years, iron-air battery have attracted a lot of attentions by scientists because of their high theoretical energy density, long life, environmentally friendly and can be applied in electric vehicles (EVs) and hybrid electric vehicles (HEVs) [1][2][3][4][5][6][7]. Although recent researches on this battery has achieved remarkable success, but due to technological challenges the iron electrode still has some shortcomings to overcome such as the passivity caused by the Fe(OH) 2 layer formed during the discharge process, hydrogen gas generated simultaneously with the reduction of iron resulting in the low utilization efficiency, actual capacity and efficiency of iron electrode is not high.…”

Abstract:To find the suitable materials for Fe/air battery anode, in this study Fe 2 O 3 electrodes were prepared using Fe 2 O 3 nanoparticles. The size and morphology of Fe 2 O 3 material were observed by scanning electron microscope (SEM). The electrochemical properties of the Fe 2 O 3 electrode in alkaline solution were investigated by using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The effects of K 2 S additive in electrolyte solution on the electrochemical characteristics of Fe 2 O 3 electrodes were also investigated. The obtained results show that the additive strongly affected on the impedance, redox reaction rate and cyclability of Fe 2 O 3 electrode.

“…The RSOFC is thus suitable for the various applications being considered for the SOFC and the SOEC. A RSOFC integrated with a redox cycle forms a rechargeable battery [97][98][99][100]. An example is a YSZ based RSOFC to provide H 2 /H 2 O cycles for a Fe/FeO redox unit in Fe-air rechargeable batteries [97,99].…”

IntroductionWorld energy consumption is projected to grow by about 56% from 2010 to 2040 (from 524 quadrillion to 820 quadrillion British thermal units (Btu)) with consumption increases from all fuel sources (fossil, nuclear, and renewable) and fossil fuels expected to continue supply much of the energy used worldwide (almost 80%) [1]. As use of fossil fuels is projected to increase, world energyrelated CO 2 emissions will grow from 31 billion metric tons in 2010 to 45 billion metric tons in 2040, a 45% increase [1]. Thus, it is expected that future energy systems should be fuel-flexible (flexibility) (to facilitate integration with any type of energy sources) and environmentally compatible (compatibility) (to reduce CO 2 emissions). In addition, such systems should have the characteristics of capability (useful for different functions), adaptability (suitable for various applications and adaptable to local energy needs), and affordability (competitive in costs) (Figure 16.1). Reversible solid oxide fuel cells (RSOFCs), being developed for hydrogen/syngas production and power generation, potentially have all those desired characteristics and, therefore, can serve as a base technology for green, flexible, and cost-competitive future energy systems [2]. This chapter provides an overview of the RSOFC, discusses its hydrogen/syngas production and power generation operations, and reviews the status of the technology and its applications. Reversible Solid Oxide Fuel Cell Overview Operating PrinciplesA RSOFC is a device that can operate efficiently in both fuel cell mode for power generation and electrolysis mode for chemical production. Thus, in fuel cell
