제목 Electrochemical Properties of Metal Nanoclusters Electrodes Containing Polyaniline Particle Supports
초록 The search for efficient and inexpensive catalyst materials is a challenging problem for all proton-exchange-membrane fuel cells (PEMFC), especially for the direct methanol fuel cells (DMFC), where a relatively high catalyst loading is still required. The common preparation techniques for catalyst layers in fuel cell electrodes start from carbon blacks covered with platinum. On the other hand, electrical conducting polymers could also be functioned as the suitable host matrices for dispersing metallic particles. In this study, polyaniline particles prepared by chemical polymerization was selected as catalyst supports to overcome the low electronic conductivity problem, and Pt-Ru nanoparticles were deposited on the support substrates. The deposited particle sizes and contents were studied to find an optimal condition to prepare the metal nanoparticles having a superior catalytic activity.
