Description
  • The state of the art high temperature PEM fuel cell technology is based on H3PO4 imbibed polymer electrolytes. The most challenging areas towards the optimization of this technology are: (i) the development of stable long lasting polymer structures with high ionic conductivity and (ii) the design and development of catalytic layers with novel structures and architectures aiming to more active and stable electrochemical interfaces with minimal Pt corrosion. In this respect the objective of the present proposal is to understand the functional operation and degradation mechanisms of high temperature H3PO4 imbibed PEM and its electrochemical interface. The degradation mechanisms will be thoroughly studied and be focused on low loading Pt or nanostructured alloyed Pt electrocatalysts and catalytic layers, which will be supported on finely dispersed or structurally organized modified carbon supports (nanotubes, pyrolytic carbon). A stable electrocatalytic layer with full metal electrocatalyst utilization a (en)
