Key features of the approach are discussed along with the technological and research challenges that need to be overcome for scale-up and commercialisation. Keywords: Solid oxide fuel cell; liquid metal anode; direct carbon fuel cell J. Electrochem. Sci.

BRETT* Electrochemical Innovation Laboratory, Centre for CO2 Technology, Department of Chemical Engineering, University College London, UK; *Intelligent Energy Ltd, Loughborough, Leicestershire, UK; *[email protected] doi: 10.5599/jese.2013.0033 Accepted: 06.03.2013 Available OnLine: 15.03.2013 Abstract: A low-cost multi-channel frequency response analyser (FRA) has been developed based on a DAQ (data acquisition)/LabVIEW interface. The system has been tested for electric and electrochemical impedance measurements. This novel association of hardware and software demonstrated performance comparable to a commercial potentiostat / FRA for passive electric circuits. The software has multichannel capabilities with minimal phase shift for 5 channels when operated below 3 kHz. When applied in active (galvanostatic) mode in conjunction with a commercial electronic load (by discharging a lead acid battery at 1.5 A) the performance was fit for purpose, providing electrochemical information to characterize the performance of the power source. Keywords: LabVIEW, multi-channel impedance, electrical circuit, fuel cell, lead acid battery J. Electrochem. Sci.

A most important aspect concerning their widespread implementation is the cost of polymeric membranes, typically perfluorinated membranes and platinum-based catalytic electrode materials, all of which are necessary to promote electrode reactions, thus increasing fuel cell energy efficiency. In this work, we present some data about non-fluorinated polyetheresulphone (PES) membranes and Pt-free catalysts, as possible substitutes of the above materials. Their electrochemical behaviour in oxygen reduction reaction in acidic media are investigated and compared with available reference materials. Keywords: ORR, Pt-free catalyst, PES, PEMFC
