摘要

The present invention discloses a composition for forming an electrode catalyst layer of a hydrogen ion exchange membrane fuel cell, an electrode catalyst layer of a hydrogen ion exchange membrane fuel cell formed therefrom, and a hydrogen ion exchange membrane fuel cell having the same. The composition for forming an electrode catalyst layer of the hydrogen ion exchange membrane fuel cell includes a conductive agent in which a metal (M) catalyst is dispersed, a hydrogen ion conducting polymer, a binder, and a hydrogen storage alloy. According to the present invention, the utilization rate of the metal (M) catalyst is improved, so that the amount of the metal catalyst used is reduced than before. As a result, an electrode catalyst layer of PEMFC can be manufactured at a lower cost than before, and a fuel cell including the electrode catalyst layer has excellent power density characteristics.
