The Potential of Non Carbon Based Catalysts for Automotive Fuel Cells

摘要

In this paper we compare the performance and stability of state of the art carbon based catalysts with non carbon based catalyst. Technically Indium-Oxide supported Platinum exhibits excellent stability under corrosion at 1.4V, with good transport properties and activity in a fuel cells electrode. However for commercial success there is a need for replacing Iridium. As one potential example we have prepared Antimony doped Tin-Oxide supported Platinum. This material is showing fundamentally promising properties, but instability of the dopant leads to a reduction in activity of the catalyst.
