“…One of the most important issues is the densification of the electrolyte layer that normally requires high sintering temperatures (normally >1,200°C for YSZ-based electrolytes), which in oxidizing atmosphere leads to serious corrosion of the metallic substrate. To solve the problem, different processing routes to fabricate electrodes and dense electrolytes on metallic supports have been employed, such as atmospheric plasma spray processing (APS) [3,4], vacuum plasma spraying (VPS) [5][6][7], pulsed laser deposition (PLD) [8], electrophoretic deposition (EPD) [9], and high temperature sintering in reducing atmosphere [1,[10][11][12].…”

Planar Metal‐Supported SOFC with Novel Cermet Anode

et al. 2011

Metal‐supported solid oxide fuel cells are expected to offer several potential advantages over conventional anode (Ni‐YSZ) supported cells. For example, increased resistance against mechanical and thermal stresses and a reduction in material costs. When Ni‐YSZ based anodes are used in metal supported SOFC, elements from the active anode layer may inter‐diffuse with the metallic support during sintering. This work illustrates how the inter‐diffusion problem can be circumvented by using an alternative anode design based on porous and electronically conducting layers, into which electrocatalytically active materials are infiltrated after sintering. The paper presents the electrochemical performance and durability of the novel planar metal‐supported SOFC design. The electrode performance on symmetrical cells has also been evaluated. The novel cell and anode design shows a promising performance and durability at a broad range of temperatures and is especially suitable for intermediate temperature operation at around 650 °C.

“…The cell performance was very promising, showing significantly lower or at least comparable area specific resistance (ASR) values than that of many other metal supported SOFCs presented so far in the literature (see e.g ref. (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11) Figure 5. The degradation rate observed during testing at 0.25 Acm -2 was <5 % / 1000 h based on the change in cell voltage during the testing period.…”

Metal-supported solid oxide fuel cells are expected to offer several potential advantages over conventional anode (Ni-YSZ) supported cells, such as increased resistance against mechanical and thermal stresses and a reduction in materials cost. When Ni-YSZ based anodes are used in metal supported SOFC, electrode material from the active anode layer may interdiffuse with the metallic support during sintering. The purpose of this work is to illustrate how the interdiffusion problem can be circumvented by using an alternative anode design based on porous and electronically conducting layers, into which electrocatalytically active materials are infiltrated after sintering. The paper presents the recent results on the electrochemical performance and durability of the novel planar metal-supported SOFC design. The results presented in the paper show that the novel cell and anode design has a promising performance and durability at a broad range of temperatures and is especially suitable for intermediate temperature operation.

“…There is rising interest in using porous metals as supports for solid oxide fuel cells (SOFCs) [1,2,3,4], which represent an emerging technology for efficient and low-emission power generation. A SOFC is a multilayered solid device that converts chemical energy in fuels directly into electricity through electrochemical reactions at elevated temperatures.…”

The effective steady-state creep response of porous metals is studied by numerical homogenization and analytical modeling in this paper. The numerical homogenization is based on finite element models of three-dimensional microstructures directly reconstructed from tomographic images. The effect of model size, representativeness, and boundary conditions on the numerical results are investigated. Two analytical models for creep rate of porous bodies are derived by extending the Hashin-Shtrikman bound and the Ramakrishnan-Arunchalam model in linear elasticity to steady-state creep based on nonlinear homogenization. The numerical homogenization prediction and analytical models obtained in this work are compared against reported measurements and models. The relationship between creep rate and porosity computed by homogenization is found to be bounded by the Hodge-Dunand model and the Hashin-Shtrikman creep model, and closely matched by the Gibson-Ashby compression and the Ramakrishnan-Arunchalam creep models.
