▎ 摘　　要

NOVELTY - Production of catalyst carrier involves dissolving a transition metal chalcogen compound precursor in a thiourea solution, synthesizing the transition metal chalcogen compound through hydrothermal synthesis, drying the transition metal chalcogen compound after washing, and dispersing and mixing graphene or carbon nanotubes (CNT) in the transition metal chalcogen compound. USE - Production of carrier for supporting catalyst used as fuel electrode catalyst for fuel cell (all claimed). Uses include but are not limited to oxidation and reduction reaction, electrolyte, electrolyte membrane, current collector, and bipolar plate. ADVANTAGE - The catalyst carrier contains the transition metal chalcogen compound can improve the catalyst support performance through optimization, fuel cell performance, high electroconductivity, increased large surface area, and high stability within a fuel cell operating environment and voltage range. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) the catalyst carrier; (2) production of catalyst; (3) the catalyst; and (4) a fuel cell.
