Abstract
Hydrogen-producing fuel cell systems with load-responsive feedstock delivery systems, and methods for regulating the delivery of feedstock to the hydrogen-producing region of a fuel cell system. The fuel cell systems include a control system that is adapted to monitor and selectively regulate the rate at which the feedstock is delivered to a hydrogen-producing region of a hydrogen generation assembly. The control systems, and corresponding methods, include feed-forward and feedback control portions that cooperatively regulate the rate at which the feed stream is delivered to the hydrogen generation assembly responsive at least in part, if not completely, to the fuel cell stack's demand for hydrogen gas and the rate at which the produced hydrogen gas is consumed by the fuel cell stack.
