Abstract
A synthesis route is reported based on the electrospinning technique that leads to NbC nanotubes with the appropriate properties for an electrocatalyst support for PEMFC cathode. The NbC nanotubes were successfully catalysed with 3 nm Pt particles by a microwave assisted polyol method so as to be investigated as electrocatalyst support. The accelerated stress test (AST) described in this contribution highlights the high stability of the novel NbC based support in comparison with a commercial 50 % Pt/C with similar the electrochemical surface area (ECSA).
