  • Hydrogen system and method for starting up a hydrogen system
    Patent number: 8557460
    Abstract: A hydrogen system (10) comprising a reformer (12), in which a vaporized hydrocarbon fuel (50) is reformed to yield a reformate gas (62) comprising hydrogen, and a hydrogen consumer (40), the reformer and the hydrogen consumer being arranged in fluid communication such that the reformate gas can be fed to the hydrogen consumer, the hydrogen consumer, when in use, consuming at least a part of the hydrogen produced by the reformer wherein the hydrogen system further comprises:—an off gas burner (35) which is arranged such that it is in fluid communication with the hydrogen consumer and a first heat exchanger (21), in which offgas burner, when in use, remaining reformate gas in offgas from the hydrogen consumer is combusted, producing exhaust gas (53) which is passed through the first heat exchanger;—at least one air pump (30) which is arranged such that it is in fluid communication with the reformer and the offgas burner, the at least one air pump, when in use, supplying air to said reformer and offgas burner,—a
