摘要： The present invention provides a catalyst for a polymer electrolyte fuel cell including catalyst particles made of platinum supported on a carbon powder carrier, wherein the carbon powder carrier includes 0.7 to 3.0 mmol/g (based on the weight of the carrier) of a hydrophilic group bonded thereto; and the platinum particles have an average particle size of 3.5 to 8.0 nm and the platinum specific surface area based on CO adsorption (COMSA) of 40 to 100 m 2 /g. The catalyst for a polymer electrolyte fuel cell according to the present invention is a catalyst excellent in initial activity and satisfactory in durability.
