摘要：

The influence of decomposition products from perfluorosulfonic acid (PFSA) membrane on fuel cell performance was investigated by a proposed method. Aqueous solutions of various model compounds, acting as possible decomposition products from the PFSA membrane, were injected directly into a pristine cell, and changes in the cell performance were measured. The injection of sulfuric acid (SA) and perfluorocarboxylic acids (PFCAs) decreased the cell voltage, which was attributed to a decrease in the mass activity for the oxidation reduction reaction (ORR). It was found that specifically adsorbed SA and PFCAs blocked the ORR at practical cathode potentials (>0.6 V). (C) 2008 The Electrochemical Society.
