Title:
FLUORINE-CONTAINING CARBON PARTICLES, METHOD FOR PRODUCING SAME, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2016/190248
Kind Code:
A1
Abstract:
Provided are: fluorine-containing carbon particles, a carbon support, an electrode catalyst, a catalyst layer forming coating, and an electrode with which a membrane electrode assembly can be obtained that has excellent power generation performance and that is less prone to reduction of the power generation performance after repeatedly starting up and shutting down a fuel cell; and the membrane electrode assembly. Fluorine-containing carbon particles are used which satisfy the relationship, 0.8≤(F/C)s/(F/C)w≤1.2 (provided that (F/C)s is a ratio of the number of atoms of fluorine to the number of atoms of carbon on the outer surface of the fluorine-containing carbon particles, and (F/C)w is a ratio of the number of atoms of fluorine to the number of atoms of carbon over the entirety of the fluorine-containing carbon particles).
