The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

Characterisation of a direct methanol fuel cell using an anode fabricated by thermal decomposition from Pt-Ru chloro-complex on Ti mesh is described. The polarisation characteristic of the resultant membrane electrode assembly is compared with that of a conventional MEA with an anode, consisting of a catalyst layer, a microporous layer and a wet-proof-treated carbon paper. Electrode characterisation was carried out using XRD, SEM and EDX analyses. In 1 M methanol solution, the MEA with the catalysed Ti mesh anode gave a power performance comparable with that of the conventional anode at 90°C. However, in 0.5 M methanol solution the former showed much higher power density than the latter, indicating high utilisation of methanol fuel.
