Preparation and characterization of Ni-plated polytetrafluoroethylene plate as an electrode for alkaline fuel cell
At about 50 wt% Ni content, Ni-plated polytetrafluoroethylene (Ni-PTFE) particles show conductivity of 300 S m(-1) when plated oil 25 mu m PTFE particles. For this study, Ni-PTFE particles were formed into the Ni-PTFE plate using heat treatment at 350 degrees C after 300 kg cm(-2) pressing. The Ni-PTFE plate displayed electrical conductivity and gas permeability. The plate was used as an electrode in an alkaline fuel cell (AFC). In terms of the current density, AFC using the Ni-PTFE electrode plated with Pt or Pd by immersion plating showed improved performance. (C) 2008 Elsevier B.V. All rights reserved.
