Howey DA, Yufit V, Mitcheson PD, Offer GJ, Brandon NPet al., 2014, Impedance measurement for advanced battery management systems

© 2013 IEEE. We present a fast, low-cost approach to measure battery impedance 'on-line' in a vehicle across a range of frequencies (1-2000 Hz). Impedance measurement has promise for improving battery management since it is a very effective non-invasive method of diagnosing the internal state of an electrochemical cell. It is useful for estimating temperature, ageing, state of charge (SOC) and for fault detection. The aim of this paper is firstly to explore the usefulness of impedance for estimating SOC, focusing on lithium-ion iron phosphate (LFP) and nickel manganese cobalt oxide (NMC) cells, and secondly to demonstrate the performance of a low cost impedance measurement system that uses an existing motor drive similar to that of an electric vehicle to excite the battery current. We find that measurements made with this system are accurate to within a few per cent of results from an expensive, bulky commercial system. For SOC estimation in NMC cells, the charge transfer resistance and SEI layer resistance vary significantly with SOC. In LFP cells the parameter variation is much less obvious, although the double layer capacitance of the full pack may be a useful indicator of SOC.

Kishimoto M, Lomberg M, Ruiz-Trejo E, Brandon NPet al., 2014, Towards the microstructural optimisation of solid oxide fuel cell electrodes

One-dimensional numerical simulation and microstructural analysis of solid oxide fuel cell (SOFC) electrodes are carried out to investigate the effect of the characteristic length scale of the porous electrodes on the performance. The sensitivity of the current density is analysed over a wide range of triple-phase boundary (TPB) density and mean-pore size, which affect the electrochemical reaction and gas transport. Comparison between conventional electrodes and nano-particle infiltrated electrodes reveals that reducing characteristic length scale in the conventional electrodes helps improve the electrode performance by reducing the reaction resistance; however, introducing nano particles into the electrodes is expected to be more effective as it has a potential to increase the TPB density whilst keeping better gaseous transport through the electrodes. The three-dimensional microstructures of both types of electrodes are obtained with focused ion beam scanning electron microscopy and provide useful microstructural information that supports the numerical analysis.

Mazur C, Contestabile M, Offer GJ, Brandon NPet al., 2014, Understanding the automotive industry: German OEM behaviour during the last 20 years and its implications

© 2013 IEEE. This work presents a study of how the automotive industry has responded in the last 20 years to pressures driven by economic and environmental issues, and by the transition towards electric mobility. Timelines for the major German automotive OEMs are presented to understand the industry's behaviour in the past in order to design suitable policies that are appropriate to reach future goals around the electrification of road transport. Based upon a comparison of the pressures arising in the automotive sector and the companies' behaviour with regard to technology choice and R&D, a set of hypotheses concerning this behaviour is then presented.

A novel metal-supported solid oxide fuel cell has been developed that is capable of operating at temperatures of 500-600 °C. The rationale behind the materials used to construct this fuel cell type is given, and results are presented from cell testing on hydrogen and reformed natural gas, including durability trials of some 2500 h duration. This new fuel cell variant is shown to be tolerant of carbon monoxide, durable, robust to thermal and redox cycling, and capable of delivering technologically relevant power densities. © 2013 ASM International.

Copyright © 2013 Delta Energy and Environment. The work investigates the catalytic properties of different SOFC anode substrates towards the chemical conversion of methane and carbon dioxide into H2 and CO-rich mixtures. The analysis is carried out by means of experiments in micro-reactor configuration. A mass spectrometer is provided to analyze the composition of the gas mixture leaving the reactor and thus allowing the evaluation of methane conversion rate. Furthermore, Temperature Programmed Oxidation (TPO) experiments are performed on the anode samples aiming at the analysis of material activity towards the cracking reaction of methane. Anode substrates based on different materials and microstructures are taken into account. The work features the effect of materials' composition and microstructure on the methane conversion rate and carbon cracking.
