Title:
CARBON BLACK AND FUEL CELL CATALYST PREPARED THEREWITH
Document Type and Number:
Japanese Patent JP2017206568
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide carbon black having high dispersibility and suitable for a fuel cell catalyst carrier.SOLUTION: Carbon black has a DBP absorption of 200 ml/100g or more; a ratio of the DBP absorption to a specific surface of 0.60 or less (DBP absorption (ml/100 g)/specific surface (m/g)); a sulfur content of 50 ppm or less; and a bulk density of 0.050 g/cmor less. A fuel cell catalyst is obtained by carrying platinum particles and/or platinum alloy particles on the carbon black.SELECTED DRAWING: None
