Desulfurizer, hydrogen generation apparatus, fuel cell power generating system, and desulfurizing agent cartridge

A desulfurizer comprising:

• an outer container that is provided in a flow path of material, and has an outer-container inlet into which the material flows, and an outer-container outlet from which the material flows out, and
• an inner container that has a desulfurizing section filled with a desulfurizing agent for removing an odor component in the material, and is removably disposed in the outer container,
• wherein the inner container has
• an inner-container inlet that is communicated to the outer-container inlet, and allows inflow of the material into the desulfurizing section,
• an inner-container outlet that is communicated to the outer-container outlet, and allows outflow of the material from the desulfurizing section, and
• partition portions provided in the inner-container inlet and the inner-container outlet respectively, and
• when the inner container is disposed in the outer container, each of the partition portions is moved or deformed by an effect of each of the outer-container inlet and the outer-container outlet, so that communication is made between the outer-container inlet and the inner-container inlet, and between the inner-container outlet and the outer-container outlet.
