A coloration agent for carbonyl sulfide which comprises a metal oxide and, carried thereon, at least one metal component selected from among a cerium component, a silver component, a copper component, a nickel component and an iron component, or comprises at least one metal oxide selected from among a cerium oxide, a silver oxide, a copper oxide, a nickel oxide and an iron oxide; a detecting means for carbonyl sulfide using said coloration agent; and a fuel cell system equipped with said detecting means. The above coloration agent is capable of being colored by carbonyl sulfide, exhibits excellent capability performance as a coloration agent for carbonyl sulfide in a hydrocarbon fuel, and thus allows the visual judgment of the life of a desulfurizing agent.

L~invention concerne un agent de coloration pour sulfure de carbonyle, comprenant un oxyde métallique, lequel porte au moins un composant métallique parmi un composant de cérium, un composant d~argent, un composant de cuivre, un composant de nickel et un composant de fer, ou comprend au moins un oxyde métallique parmi un oxyde de cérium, un oxyde d~argent, un oxyde de cuivre, un oxyde de nickel et un oxyde de fer ; des moyens de détection du sulfure de carbonyle utilisant ledit agent de coloration ; et un système de pile à combustible équipé desdits moyens de détection. L~agent de coloration mentionné précédemment peut être coloré par du sulfure de carbonyle, présente d~excellentes propriétés en tant qu~agent de coloration pour le sulfure de carbonyle dans un hydrocarbure, et permet ainsi d~évaluer à l~AEil nu la durée de vie d~un agent de désulfuration.
