CORE-SHELL CATALYSTS AND METHOD FOR PRODUCING THE SAME |
摘要 |
The present invention is to provide core-shell catalysts which are configured to be able to increase the performance of a unit cell of a fuel cell, and a method for producing the core-shell catalysts. Disclosed are core-shell catalysts and method for producing the same, the core-shell catalysts comprising a core containing palladium and a shell containing platinum and covering the core, wherein, in a number-based particle size frequency distribution, an average particle size is 4.70 nm or less; a standard deviation is 2.00 nm or less; and a frequency of a particle size of 5.00 nm or less is 55% or more. |
