ELECTRODE CATALYST FOR FUEL CELL, METHOD FOR PRODUCING THE SAME, AND POLYMER ELECTROLYTE FUEL CELL USING THE SAME

摘要

An electrode catalyst for a fuel cell consists principally of a carbon support, and a platinum catalyst or a platinum-alloy catalyst supported on the carbon support. In the electrode catalyst, at least 0.7 mmol of an acid per gram of the electrode catalyst is present on the carbon support.
