High performance Pt-free cathode catalysts for polymer electrolyte membrane fuel cells prepared from widely available chemicals

Abstract

A high performance Pt-free cathode catalyst for polymer electrolyte fuel cells has been synthesized by the multi-step pyrolysis of polyimide fine particles with a diameter of about 100 nm. This cathode catalyst exhibits good fuel cell performance (1.0 A cm-2 at 0.6 V and 80 °C) along with promising durability. This journal is © the Partner Organisations 2014.
