DESULFURIZING DEVICE FOR FUEL CELL, AND FUEL CELL SYSTEM COMPRISING THE SAME

摘要

A desulfurizer of a fuel system is provided to improve a desulfurization efficiency by including a dewetting part which selectively absorbs the moisture, thereby reducing the volume of a desulfurizing agent and cutting down costs. A desulfurizer(20) for a fuel cell comprises a dewetting unit which selectively absorbs the moisture included in the fuel(23) and a desulfurization unit(25) absorbing the sulfide included in the fuel passing through the dewetting part. The dewetting part and desulfurization unit. The dewetting unit and desulfurization unit are formed in a volume ratio of 1 : 10 - 5 : 3.
