Abstract
An automotive fuel cell stack includes anodes and cathodes, and a controller that, after receiving data indicating that load current demand is within a first pre-determined range, modulates a flow rate of air to the cathodes between zero and a pre-determined value until a cell output voltage achieves a value falling within a second pre-determined range greater than zero.
