<p>A method is proposed for increasing the operational efficiency of a fuel cell power plant (10) including a cell stack assembly (12) comprised of a plurality of fuel cells in electrical communication with one another. The cell stack assembly includes a fuel inlet manifold (26) and a fuel exit manifold (28) for accepting and exhausting, respectively, a reactant fuel stream. The proposed method includes providing the cell stack assembly with the reactant fuel stream, sealing the fuel exhaust manifold for a first predetermined time period, thereby preventing the reactant fuel stream from exiting the cell stack assembly and opening the fuel exhaust manifold for a second predetermined time period.</p> |
