Abstract
A fuel cell system includes a hot box, a stack of fuel cells disposed in the hot box, and a desulfurization subsystem. The desulfurization subsystem may include a sulfur adsorption reactor containing a metal oxide, such as ZnO, configured to adsorb sulfur species from fuel, a first fuel conduit configured to provide fuel to the reactor, and a second fuel conduit configured to receive fuel from the reactor. The desulfurization subsystem may be configured to heat the reactor to an operating temperature ranging from about 200° C. to about 450° C., using heat generated in the hot box.
