Abstract

The invention is an operating system for a fuel cell power plant that includes at least one fuel cell for producing electrical energy from a reducing and oxidant fluid and fuel processing components including a reformer and a burner for processing a hydrocarbon fuel into the reducing fluid, and a direct mass and heat transfer device secured in fluid communication with both a process oxidant stream and a plant exhaust passage, so that the device directly transfers mass such as water exiting the plant in a plant exhaust stream back into the plant within the process oxidant stream. The invention also includes a split oxidant passage that directs the process oxidant stream through the fuel cell and a reformer feed portion of the process oxidant stream into fluid communication with the fuel processing components. The system may also include an anode exhaust passage that directs an anode exhaust from the fuel cell into the burner, then directs the oxidized anode exhaust stream from the burner in heat exchange relationship with the reformer feed portion.
