The Steam-Iron process, based on the redox reaction of iron oxides (Fe3O4 + 4H(2) <-> 3Fe+4H(2)O), is an interesting alternative to other methods of storing and generating pure hydrogen. In order to evaluate the ability of the Steam-Iron process to supply hydrogen to a solid oxide fuel cell (SOFC), a mathematical model for the oxidation process in a fixed bed reactor has been developed and is used to estimate the behaviour of the reactor under various operating conditions (e.g. amount of iron, steam flow rate, temperature). As a result of the simulations, information is provided for the preliminary design of the reactor and the selection of optimal reaction conditions. Furthermore, we have shown that the Steam-Iron reactor can be successfully integrated with an SOFC, and two system options have been explored to determine the overall system efficiency.

Mermelstein J, Millan-Agorio M, Brandon NP, 2009, The impact and mitigation of carbon formation on Ni-YSZ anodes from biomass gasification tars, Pages: 111-117, ISSN: 1938-5862
The combination of Solid Oxide Fuel Cells (SOFCs) and biomass gasification has the potential to become an attractive technology for the production of clean renewable energy. However the impact of tars, formed during biomass gasification, on the performance and durability of SOFC anodes has not been well established experimentally. This paper reports on an experimental study assessment of the performance and mitigation of carbon formation on the anodes of SOFC button cells from synthetic model tars arising from the gasification of biomass material. The anode material was a 60:40 wt.% NiO/YSZ cermet, which was tested in a synthetically generated syngas containing a concentration of up to 15 g/Nm3 biomass gasification tars. It was found that carbon formation in dry conditions significantly damaged the anode of the fuel cell resulting in decreased cell performance and excessive anode polarization resistances. These effects were reduced by applying a load to the cell, and were essentially inhibited once the steam content of the input fuel was > 2%. © The Electrochemical Society.

In solid oxide fuel cells (SOFC) the redox reactions are supported by composite porous materials and, therefore, the electrochemical activity of an electrode is a direct function of its microstructure. Ni-YSZ (Yttria Stabilized Zirconia) is a common choice for the anode material in SOFC. Recently advances in tomographic techniques have enabled researchers to probe electrode microstructures providing unprecedented access to a wealth of microstructural information regarding the distribution of ionic, electronic and pore phases in three dimensions. In this paper nano-scale X-ray Computed Tomography (nCT) and Focused Ion Beam (FIB) techniques have been used to characterize microstructures from the same Ni-YSZ anode sample, 3D reconstruction from both techniques are presented and a quantitative and qualitative comparison is provided. An advanced technique for sample preparation for nCT is also presented. ©The Electrochemical Society.

Chen XJ, Liu QL, Chan SH, et al., 2007, High-performance cathode-supported SOFC with perovskite anode operating in weakly humidified hydrogen and methane, Fuel Cells Bulletin, Vol: 2007, Pages: 12-16, ISSN: 1464-2859
A high-performance, cathode-supported solid oxide fuel cell (SOFC), suitable for operating in weakly humidified hydrogen and methane, has been developed. The SOFC is essentially made up of a YSZ-LSM composite supporting cathode, a thin YSZ film electrolyte, and a GDC-impregnated La0.75Sr0.25Cr0.5Mn0.5O3 (LSCM) anode. A gas-tight thin YSZ film (27 μm) was formed during the co-sintering of the cathode/electrolyte bilayer at 1200°C. The cathode-supported SOFC developed in this study showed encouraging performance with maximum power density of 0.182, 0.419, 0.628 and 0.818 W/cm2 in air/3% H2O-97% H2 (and 0.06, 0.158, 0.221 and 0.352 W/cm2 in air/3% H2O-97% CH4) at 750, 800, 850 and 900°C, respectively. Such performance is close to that of the cathode-supported cell (0.42 W/cm2 versus 0.455 W/cm2 in humidified H2 at 800°C) developed by Yamahara et al.[1] [DOI: 10.1016/j.ssi.2004.09.023] with a Co-infiltrated supporting LSM-YSZ cathode, an (Sc2O3)0.1(Y2O3)0.01(ZrO2)0.89 (SYSZ) electrolyte of 15 μm thickness and an SYSZ/Ni anode, indicating that the performance of the GDC-impregnated LSCM anode is comparable to that made of Ni cermet while stable in weakly humidified methane fuel. © 2007 Elsevier Ltd.
