Numerical investigation of the chemical and electrochemical characteristics of planar solid oxide fuelcell with direct internal reforming

Yuzhang WANG, Shilie WENG, Yiwu WENG

《能源前沿（英文）》 2011年第5卷第2期页码 195-206 doi: 10.1007/s11708-011-0148-8

摘要： A fully three-dimensional mathematical model of a planar solid oxide fuel cell (SOFC) with complete direct internal steam reforming was constructed to investigate the chemical and electrochemical characteristics of the porous-electrode-supported (PES)-SOFC developed by the Central Research Institute of Electric Power Industry of Japan. The effective kinetic models developed over the Ni/YSZ anode takes into account the heat transfer and species diffusion limitations in this porous anode. The models were used to simulate the methane steam reforming processes at the co- and counter-flow patterns. The results show that the flow patterns of gas and air have certain effects on cell performance. The cell at the counter-flow has a higher output voltage and output power density at the same operating conditions. At the counter-flow, however, a high hotspot temperature is observed in the anode with a non-fixed position, even when the air inlet flow rate is increased. This is disadvantageous to the cell. Both cell voltage and power density decrease with increased air flow rate.

Part-load, startup, and shutdown strategies of a solid oxide fuel cell-gas turbine hybrid system

Yang LI, Yiwu WENG, Shilie WENG

《能源前沿（英文）》 2011年第5卷第2期页码 181-194 doi: 10.1007/s11708-011-0149-7

摘要： Current work on the performance of a solid oxide fuel cell (SOFC) and gas turbine hybrid system is presented. Each component model developed and applied is mathematically defined. The electrochemical performance of single SOFC with different fuels is tested. Experimental results are used to validate the SOFC mathematical model. Based on the simulation model, a safe operation regime of the hybrid system is accurately plotted first. Three different part-load strategies are introduced and used to analyze the part-load performance of the hybrid system using the safe regime. Another major objective of this paper is to introduce a suitable startup and shutdown strategy for the hybrid system. The sequences for the startup and shutdown are proposed in detail, and the system responses are acquired with the simulation model. Hydrogen is used instead of methane during the startup and shutdown process. Thus, the supply of externally generated steam is not needed for the reforming reaction. The gas turbine is driven by complementary fuel and supplies compressed air to heat up or cool down the SOFC stack operating temperature. The dynamic simulation results show that smooth cooling and heating of the cell stack can be accomplished without external electrical power.

Performance comparison of cocurrent and countercurrent flow solid oxide fuel cells

Huisheng ZHANG, Shilie WENG, Ming SU

《能源前沿（英文）》 2011年第5卷第2期页码 207-213 doi: 10.1007/s11708-011-0151-0

摘要： Solid oxide fuel cell (SOFC) is a complicated system with heat and mass transfer as well as electrochemical reactions. The flowing configuration of fuel and oxidants in the fuel cell will greatly affect the performance of the fuel cell stack. Based on the developed mathematical model of direct internal reforming SOFC, this paper established a distributed parameters simulation model for cocurrent and countercurrent types of SOFC based on the volume-resistance characteristic modeling method. The steady-state distribution characteristics and dynamic performances were compared and were analyzed for cocurrent and countercurrent types of SOFCs. The results indicate that the cocurrent configuration of SOFC is more suitable with regard to performance and safety.

A performance analysis of integrated solid oxide fuel cell and heat recovery steam generator for IGFC

Souman RUDRA, H. T. KIM, Jinwook LEE, L. ROSENDAHL,

《能源前沿（英文）》 2010年第4卷第3期页码 402-413 doi: 10.1007/s11708-010-0122-x

摘要： Solid oxide fuel cell (SOFC) is a promising technology for electricity generation. Sulfur-free syngas from a gas-cleaning unit serves as fuel for SOFC in integrated gasification fuel cell (IGFC) power plants. It converts the chemical energy of fuel gas directly into electric energy, thus high efficiencies can be achieved. The outputs from SOFC can be utilized by heat recovery steam generator (HRSG), which drives the steam turbine for electricity production. The SOFC stack model was developed using the process flow sheet simulator Aspen Plus, which is of the equilibrium type. Various ranges of syngas properties gathered from different literature were used for the simulation. The results indicate a trade-off efficiency and power with respect to a variety of SOFC inputs. The HRSG located after SOFC was included in the current simulation study with various operating parameters. This paper describes IGFC power plants, particularly the optimization of HRSG to improve the efficiency of the heat recovery from the SOFC exhaust gas and to maximize the power production in the steam cycle in the IGFC system. HRSG output from different pressure levels varies depending on the SOFC output. The steam turbine efficiency was calculated for measuring the total power plant output. The aim of this paper is to provide a simulation model for the optimal selection of the operative parameters of HRSG and SOFC for the IGFC system by comparing it with other models. The simulation model should be flexible enough for use in future development and capable of predicting system performance under various operating conditions.

Plasma spray coating on interconnector toward promoted solid oxide fuel cells and solid oxide electrolysis

《能源前沿（英文）》 doi: 10.1007/s11708-023-0901-9

摘要： Interconnector is a critical component to construct solid oxide cells (SOCs) stack. Oxidation of metallic interconnectors and Cr poisoning caused by oxidation are important factors that lead to long-term performance degradation of SOCs. Coating on the interconnector surface is an important approach to inhibit the oxidation and Cr migration of the interconnector. Herein, (La_0.75Sr_0.25)_0.95MnO_3–δ (LSM) and Mn_1.5Co_1.5O₄ (MCO) are used to fabricate the coatings of interconnector. Two advanced thermal spray technology, atmospheric plasma spraying (APS) and low-pressure plasma spray (LPPS), are adopted for the coating preparation. The electrochemical performance, rising and cooling cycle stability, and Cr diffusion inhibition performance of the coatings are tested and evaluated. The result indicates that MCO can generate more uniform and denser coatings than LSM. In addition, MCO coatings prepared by LPPS shows the best electrochemical performance, rising and cooling cycle stability, and Cr diffusion inhibition. The initial area specific resistance (ASR) is 0.0027 Ω·cm² at 800 °C. After 4 cooling cycle tests, the ASR increases to 0.0032 Ω·cm² but lower than other samples. Meanwhile, the relative intense of Cr at the interface of SUS430 with MCO coatings fabricated by LPPS is lower than that of MCO fabricated by APS after 4 rising and cooling cycle operations, showing more favorable Cr diffusion inhibition performance.

《中国工程科学》 2013年第15卷第2期页码 88-97

摘要：固体氧化物燃料电池（SOFC）具有高能量转化效率和低污染排放，被认为是未来能源经济的基石。其中，以质子导体作为电解质的固体氧化物燃料电池（H-SOFC）由于具有高燃料利用率、高理论电动势、高离子迁移数以及低传导活化能，因而备受关注。然而，与氧离子导体固体氧化物燃料电池（O-SOFC）相比，H-SOFC的材料选择和理论体系还处于初级阶段，尤其是H-SOFC的阴极。在H-SOFC中，氢气在阳极被氧化，形成质子，通过电解质迁移到阴极，而后与氧进行电极反应生成水，其阴极的电极过程比O-SOFC更为复杂。寻找高性能的阴极材料和探索H-SOFC中的阴极反应机理，对于H-SOFC的发展具有重要的意义。

摘要：在各种燃料电池中，固体氧化物燃料电池（SOFC）可以直接使用各种含碳燃料，很容易与现有能源资源供应系统兼容，一次发电效率高（50 %～60 %）；SOFC采用全固态结构，长期稳定性好；不使用贵金属催化剂SOFC尤其适用于分布式发电系统和动力电源系统。基于我国能源结构的现状和稀土资源优势，很有必要发展碳基燃料SOFC。在SOFC从示范运行逐步走向产业化应用的过程中，迫切需要进一步提高其长期稳定性并降低成本，所以今后的研究重点是碳基燃料SOFC关键材料和系统集成创新，解决其中的材料设计和制备、碳基燃料反应特性、电池构造、理论模拟、系统集成与运行过程中的基础科学和技术问题，为高效率、低成本、稳定可靠的碳基燃料SOFC系统产业化奠定基础。

Brazing of ceramic-to-ceramic and ceramic-to-metal joints in air

Kirsten BOBZIN, Thomas SCHLAEFER, Lidong ZHAO, Nils KOPP, Arne SCHLEGEL

《机械工程前沿（英文）》 2010年第5卷第2期页码 125-129 doi: 10.1007/s11465-010-0007-z

摘要： Reactive air brazing (RAB) is an emerging technology for the production of ceramic-to-ceramic and ceramic-to-metal joints. In this study, RAB was investigated with respect to the potential applications for solid oxide fuel cells (SOFCs) as one example of use. It was found that alumina could be well brazed by RAB with AgCu and AgCuTi brazes. Both braze composition and brazing temperature influenced significantly the wetting behavior and their mechanism of wetting. AgCu and AgCuTi braze alloys could also be used to produce brazed joints with the SOFC materials ceramic yttria stabilized zirconia and steel X1CrTiLa22. However, CuO reacts with the steel, forming a brittle oxide layer on the steel surface, which is undesirable for SOFC applications. The first trials with Ag0.5Al showed a promising solution.
