Abstract
An improved catalyst support can be provided by a process for producing a carbon fiber composite which comprises: a step of subjecting metal fine particles of either at least one metal or a compound containing the metal to reductive deposition on fine cellulose having carboxyl groups on the crystal surface to make a composite composed of both the fine cellulose and the metal fine particles; and a step of carbonizing the fine cellulose of the composite to prepare a carbon fiber composite. The invention also relates to a carbon fiber composite made by the process, a catalyst support, and a polymer electrolyte fuel cell.
