A catalyst carrier, an electrode catalyst, an electrode including the catalyst, a membrane electrode assembly including the electrode, a fuel cell including the membrane electrode assembly, and a method for producing the catalyst carrier. The catalyst carrier includes a carbon material having a chain structure including a chain of carbon particles. The catalyst carrier contains a titanium compound-carbon composite particle in which carbon encloses a titanium compound particle. The molar ratios of a carbon element, a nitrogen element, and an oxygen element to a titanium element taken as 1 in the catalyst carrier are more than 0 and 50 or less, more than 0 and 2 or less, and more than 0 and 3 or less, respectively.

Catalyst carrier, method for producing catalyst carrier, and use of catalyst carrier

A catalyst carrier, an electrode catalyst, an electrode including the catalyst, a membrane electrode assembly including the electrode, and a fuel cell including the membrane electrode assembly. The catalyst carrier includes a carbon material having a chain structure including a chain of carbon particles, and an oxide-carbon composite particle in which a carbon particle encloses a particle of an oxide of a group IV element on the periodic table, the oxide-carbon composite particle being contained in the carbon material. The catalyst carrier has a BET specific surface area of 450 to 1100 m/g.
