Abstract
An electrode catalyst for fuel cells, a method of preparing the electrode catalyst, and a fuel cell including the electrode containing the electrode catalyst have been improved. The electrode catalyst includes a beryllium (Be) oxide catalyst, which oxidizes carbon monoxide included in a fuel gas into carbon dioxide, and a platinum (Pt) based catalyst. Thus, loss in catalytic activity of the Pt-based catalyst due to carbon monoxide is decreased, and the activity and life of the fuel cell including the electrode catalyst are improved.
