Summary:A method and device for operating a fuel cell system. The device includes a flowfield plate that includes a header section and a channel section. The header section includes inlet flowpaths and outlet flowpaths, where the inlets formed in the header section are fluidly decoupled from one another, as are the outlets. The channel section is divided into multiple circuits, each dedicated to a corresponding inlet and outlet. The circuits may be of different flow capacities, and may be operated independently of one another, making the device particularly adapted to both full and part-power operation.
