Pt Pt/C catalyst electrode with Pt double layers sturcture for polymer electrolyte membrane fuel cell and preparation method thereof

摘要

The present invention relates to a Pt layer dual structure catalyst electrode for a polymer electrolyte membrane fuel cell and a method for manufacturing the same. In particular, a Pt layer for a polymer electrolyte membrane fuel cell that can improve current density by minimizing Pt loading and maximizing Pt catalyst utilization. A dual structure electrode and a method for manufacturing the same, comprising: a gas diffusion layer; A Pt / C catalyst dispersion layer formed on the gas diffusion layer; And a Pt concentration layer made of Pt nanoparticles deposited by electrophoretic precipitation on the Pt / C catalyst dispersion layer.
