Abstract
A method for operating a fuel cell power plant to supply power to an internal load and an external load, includes the steps of evaluating power needs of the internal and external loads to determine a fixed IDC value sufficient to supply the needs; providing auxiliary power to the internal load and output power to the external load so as to maintain operation of the fuel cell power plant at the fixed IDC value; and adjusting at least one of the auxiliary power to the internal load and output power to the external load so as to maintain operation of the fuel cell power plant at the fixed IDC value.
Claims10
A method for operating a fuel cell power plant, comprising the steps of:
- evaluating power needs of an external load to determine a fixed IDC value sufficient to supply said needs;
- providing output power to said external load at a level provided by said fuel cell power plant at said fixed IDC value;
- and
- adjusting said output power to said external load so as to maintain operation of said fuel cell power plant and said fixed IDC value.
A method for operating a fuel cell power plant to supply power to an internal load and an external load, comprising the steps of:
- evaluating power needs of said internal and external loads to determine a fixed IDC value sufficient to supply said needs;
- providing auxiliary power to said internal load and output power to said external load so as to maintain operation of said fuel cell power plant at said fixed IDC value;
- and
- adjusting at least one of said auxiliary power to said internal load and output power to said external load so as to maintain operation of said fuel cell power plant at said fixed IDC value.
A method for operating a fuel cell power plant, comprising the steps of:
- evaluating power needs of an external load to determine a fixed IDC value sufficient to supply said needs;
- and
- operating said fuel cell power plant at substantially fixed reactant flows sufficient to provide said fixed IDC value.
