Abstract
The patent relates to fuel cell systems and controlling fuel cell systems. One fuel cell system includes at least one fuel cell stack that includes multiple different serially arranged cells. The system also includes at least one component configured to effect an operating environment of the at least one fuel cell stack. The system further includes a controller configured to operate the at least one component at a primary control point relating to one or more parameters of the operating environment. The controller is further configured to temporarily adjust the at least one component to a secondary control point relating to the one or more parameters. The controller can then re-adjust the at least one component to the primary control point. The fuel cell system can achieve greater overall performance than can be obtained without the adjusting and re-adjusting.
