Abstract

A stack current controller may be configured to request a current magnitude from a fuel cell. The current magnitude requested is based at least on a battery state of charge and is performed in a stepwise manner among a plurality of current magnitude steps, where each current magnitude step includes a debounce range with respect to at least one other current magnitude step. The stack current controller may be configured to control the fuel cell to output the requested current magnitude, determine an average current output by the fuel cell over a time period, and modify a current magnitude associated with one of the current magnitude steps based on the average current.
