Abstract
A fuel cell power system and method for identifying and compensating for variations identified in a fuel composition of a fuel cell power system, comprising the fuel cell system components selected from the group consisting of a catalytic oxidizer, a reformer, an exhaust, a fuel cell stack or system, or a combination thereof; and a control device configured to control the fuel cell system components, wherein the control device comprises a computer algorithm to indirectly correlate measurements of the fuel cell system components to a difference in the fuel composition.
Claims10
A fuel cell system comprising:
- a fuel cell stack;
- components selected from the group consisting of a catalytic oxidizer, a reformer, and an exhaust system;
- sensors configured to measure parameters associated with the components, at least one of the parameters comprising a system voltage of the fuel cell system;
- and
- a control device comprising a microprocessor configured to:
- identify at least one variation in a fuel composition of the fuel cell system based, at least in part, on a detected change in the system voltage of the measured parameters, and
- control the components to compensate for the at least one variation using a computer algorithm in response to the identified at least one variation indicating a threshold difference in the fuel composition.
