摘要：

Electrospraying of Pt/C-Nafion-alcohol dispersions was employed as a new method to deposit catalyst layers on Nafion membranes for hydrogen/oxygen(air) fuel cells. It is shown that single cells with catalyst layers obtained by electrospraying exhibit good initial performance (ca. 1 A/cm(2)@ 700mV) at 80 degrees C and 300 kPa without the need for hot-pressing of the electrode layer. Analysis of polarization losses reveals a significant contribution of mass-transport losses to the fuel cell performance for hydrogen/air fuel cells. We suggest that control of electrospray processing parameters can lead to tailored electrode structures where such mass transport losses are mitigated. (c) 2005 The Electrochemical Society.
