METHOD AND CONTROL SUB-SYSTEM FOR OPERATING A POWER GENERATION SYSTEM HAVING A FUEL-CELL

Abstract:

A method for operating a power generation system including a fuel-cell is presented. The method includes detecting a water deficient condition of the fuel-cell. The method further includes operating, in response to detecting the water deficient condition of the fuel-cell, at least one auxiliary load of the power generation system via use of an electrical current generated by the fuel-cell to maintain a steam-carbon ratio in the fuel-cell above a threshold steam-carbon ratio value. A control sub-system for operating the power generation system is also presented. Moreover, a power generation system including the fuel-cell, the least one auxiliary load, and the control sub-system is presented.
