Title:
DESULFURIZATION DEVICE AND FUEL CELL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/090865
Kind Code:
A1
Abstract:
Provided is a desulfurization device used in a fuel cell system that recovers waste heat of a cell stack using a heating medium and generates electricity by means of the cell stack using a hydrogen-containing fuel. The desulfurization device is provided with: a desulfurization unit that has a desulfurization duct housing a desulfurization catalyst, and that desulfurizes the hydrogen-containing fuel by flowing the hydrogen-containing fuel through the desulfurization duct; and a desulfurization system heat exchanger that is housed within the desulfurization duct and that is a helical duct that exchanges heat between the heating medium and the desulfurization unit by flowing the heating medium through after the heating medium has recovered cell stack waste heat. The desulfurization device is formed in a manner so that the direction of fluid flow of the desulfurization system heat exchanger and the direction of fluid flow of the desulfurization duct form a countercurrent.
