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.

The electrolysis of water is the only well established technique, capable of producing emissions-free hydrogen if used in conjunction with renewable or nuclear energy. However, the current low temperature technologies suffer from their high electricity consumption and associated cost. Steam electrolysis has the potential to reduce the required electrical power consumption through improved thermodynamics and kinetics at elevated temperatures. The temperature range of 823K to 1073K is interesting in avoiding material problems while retaining much of the benefits. The present paper introduces a one-dimensional dynamic model of a steam electrolysis cell which has been created through the modification of a previous intermediate temperature SOFC model. At 1023K, for an average current density of 7000A.m-2, preliminary steady state simulations have predicted the electricity consumption to be around 3kWh per normal m3 of hydrogen, significantly lower than that required for the low temperature cells commercially available today. Issues related to the thermal management of the cell are discussed. Copyright © (2006) by AFHYPAC.

Brett D, Brandon N, Cope S, et al., 2005, Design and control options for an intermediate temperature solid oxide fuel cell / zebra battery hybrid system for vehicle applications
The 'ABSOLUTE' project (Advance Battery Solid Oxide Fuel Cell Linked Unit to Maximise Efficiency) is a Foresight Vehicle 'Link' programme, supported by the UK DTI, that aims to bring together an intermediate temperature solid oxide fuel cell (IT-SOFC) and sodium - nickel chloride (Zebra) battery as a proof-of-concept hybrid vehicle system. Bringing this type of battery and fuel cell together for an automotive application has the following benefits:- 1. High power output, fast start-up and response time - via the battery. 2. Extended range and fuel flexibility - via the fuel cell. 3. Reduced cost by minimising the size of the fuel cell since the battery meets peak power demands The IT-SOFC (from Ceres Power Ltd.) and the Zebra battery (from Beta Research and Development Ltd.) represent technologies at the forefront of their respective fields. Zebra batteries offer high power density and excellent reliability with a proven track record in vehicles. Ceres Power have demonstrated SOFCs operating in the temperature range of 500 - 650C, which, combined with the use of metal supports, offers the prospect of a more robust, durable and cost effective system. In the first phase of the project, a scaled down system is studied consisting of a 300 W IT-SOFC and 2 k W battery. This system is controlled using a novel stack operating system, a battery management interface (BMI) and a vehicle management unit (VMU) designed by MIRA Ltd. all connected using a CAN interface. In this work we demonstrate simulated system performance, we address control issues, and we present experimental results for the hybrid battery/fuel cell system.
