ABSTRACT:
An emergency shutdown apparatus for a solid-oxide fuel cell system, including a fuel cell stack, comprises a reservoir containing a reducing fluid, a valve enabling or preventing flow of the reducing fluid from the reservoir to the fuel cell stack, a timing circuit operating and controlling the valve, and a battery powering the timing circuit. The apparatus for an emergency system shutdown is able to operate independently of the main power plant and does not require any active control from the solid-oxide fuel cell system. The disclosed apparatus is entirely a stand-alone component that may be added to any conventional solid-oxide fuel cell system. The apparatus in accordance with the invention can be recharged, allowing the same hardware to be used over and over, however, a disposable unit could be used if found to be desirable.
