Abstract: A solid oxide fuel cell system and method including a hotbox containing a fuel cell stack, a fuel supply configured to provide a fuel to the fuel cell stack, and a hydrogen supply thermally integrated with the hotbox. The hydrogen supply is configured to produce hydrogen during or shortly after the SOFC system is shutdown using residual heat of the hot box, and to provide the hydrogen to the SOFC stack such that an anode reducing environment is maintained in the stack.
