Technique and apparatus to control the transient response of a fuel cell system

摘要

A technique that is usable with a fuel cell stack includes coupling the fuel cell stack to a load, monitoring a power that is consumed by the load and determining if the power is increasing or decreasing. If the output power is increasing, a first control technique is used to control a fuel flow to the fuel cell stack, and if the output power is decreasing, a second control technique that is different from the first control technique is used to control the fuel flow to the stack.
