A desulfurizing agent and desulfurization method for hydrocarbon oils, especially kerosine for use as a raw fuel for fuel cells, and a desulfurizing agent and desulfurization method for hydrocarbons for use in oil refineries. The desulfurizing agents and desulfurization methods necessitate neither a reduction treatment nor hydrogen and can effectively remove benzothiophene compounds or thiophene compounds at a temperature of from room temperature to about 150°C. When the agent and method are applied to a fuel cell, starting and maintenance are relatively easy and the fuel cell system can be simplified. The desulfurizing agent for hydrocarbon oils is characterized by comprising a copper ingredient and a silver ingredient. The fuel cell system is characterized by employing this desulfurizing agent. |
