DESULFURIZATION SYSTEM FOR FUEL CELL, HYDROGEN PRODUCTION SYSTEM FOR FUEL CELL, FUEL CELL SYSTEM, DESULFURIZATION METHOD FOR HYDROCARBON FUEL, AND METHOD FOR PRODUCING HYDROGEN

摘要

This desulfurization system for a fuel cell is provided with a fuel supplying unit for supplying, to a later stage, a hydrocarbon fuel containing oxygen at a volume concentration of 1 ppm to 4% and a sulfur compound and having a Wobbe index of 12 to 16 kWh/m³, and a desulfurization unit having a desulfurization catalyst for desulfurizing the hydrocarbon fuel, wherein the desulfurization catalyst contains an Ag-supporting zeolite and/or a Cu-supporting zeolite.
