Abstract
The present invention is related to a mesoporous carbon molecular sieve, which can be used as a catalyst carrier capable of improving the activity of a supported catalyst and a method of preparing the same. Additionally, the invention is related to a supported catalyst employing the mesoporous carbon molecular sieve as a carrier, and a fuel cell employing the supported catalyst. The mesoporous carbon molecular sieve has an average primary particle size of less than about 500 nm, an average mesopore size in the range of about 3 nm to about 6 nm, and a surface area in the range of about 500 m2/g to about 2000 m2/g.
Claims6
