<p>A mass and heat recovery system for a fuel cell power plant (10) includes at least one fuel cell (12) for producing electrical energy, hydrocarbon fuel processing components for producing a hydrogen rich reducing fluid for the fuel cell, and a direct mass and heat transfer device (14) for recovering mass and heat leaving the plant. The fuel processing components include an auxiliary burner (46) that provides heat to generate steam and a reformer (54) for supplying hydrogen to an anode electrode. The direct mass and heat transfer device passes a process oxidant stream upstream of the plant in mass transfer relationship with a plant exhaust stream wherein an anode exhaust stream has first been burned in the auxiliary burner so that mass and heat in the plant exhaust stream transfer directly through a mass transfer medium of the device to the process oxidant stream entering the plant. The device includes a separator housing (74).</p> |
