Thin films of gas sensitive materials based on the SrFeO2.5+x non-stoichiometric perovskite family were deposited onto an interdigitated gold electrode construction device by room temperature pulsed excimer laser deposition (RT-PLD). Two films sensors based on the SrFe1-yCoyO2.5+x oxides perovskite family, with y = 0.75 and 0.5 respectively, have been presented. Their ability to very quickly respond to the presence of low concentrations of methanol makes them attractive for construction of methanol sensing devices, as gases monitoring sensors for either environmental applications, or as an automated feedback sensor for concentration measurement and control in a micro direct methanol fuel cell (μ-DMFC) power supply. In this paper, we report unpublished hitherto results first presented as poster during an Electrochemical Society Symposium session held at Queen University, Kingston, Ontario, Canada.
