Catalyst structure, process for producing same and fuel cell provided with catalyst

摘要

The present invention relates to a catalyst structure of high catalytic activity and a fuel cell of high cell output. The catalyst structure of the present invention includes a carrier (1) and nano-dots (2) formed on the carrier (1) and catalyst particles (3) formed on the nano-dots (2), wherein the difference in the lattice constant between the carrier material and the nano-dot material is between 1 and 16%.
