Title:
DESULFURIZATION DEVICE AND FUEL CELL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/090864
Kind Code:
A1
Abstract:
This desulfurization device, which is used in a fuel cell system that recovers waste heat of a cell stack using a heating medium and that generates electricity by means of the cell stack using a hydrogen-containing fuel, has a configuration characterized by: being provided with a desulfurization unit, which has a desulfurization duct housing a desulfurization catalyst and desulfurizes by flowing the hydrogen-containing fuel through the desulfurization duct, and a heat exchanger, which is disposed in a manner so as to cover the side of the desulfurization unit and has a heating medium duct that exchanges heat between the heating medium and the desulfurization unit by means of causing the flow-through of the heating medium after the heating medium has recovered cell stack waste heat; and being formed in a manner so that the direction of fluid flow of the heating medium duct and the direction of fluid flow of the desulfurization duct form a countercurrent.
