Operating procedure for fuel cell system with reformer for hydrogen production and with unit, by heating the system components at operation temperature after starting the system, and recirculating partial quantity of reformat in reformer

摘要

The operating procedure for a fuel cell system with a reformer (3) for production of hydrogen from a hydrocarbon mixture by partial oxidation and with unit (5, 7, 8) that process the reformats (4) obtained in the reformer, in which after the starting of the system, the system components such as the reformers and/or the unit are heated at operating temperature, before the system is fully operationally operated. During the heating of the system components, a partial quantity of the reformat in a state after the withdrawal from the unit is recalculated in the reformer. The operating procedure for a fuel cell system with a reformer (3) for production of hydrogen from a hydrocarbon mixture by partial oxidation and with unit (5, 7, 8) that process the reformats (4) obtained in the reformer, in which after the starting of the system, the system components such as the reformers and/or the unit are heated at operating temperature, before the system is fully operationally operated. During the heating of the system components, a partial quantity of the reformat in a state after the withdrawal from the unit is recalculated in the reformer, so that the reformers during the heating in relation to the operation mode, shows its operating temperature, with which the system based on the recirculating with higher oxygen content can be operated. The reformats to be recirculated is cooled-off and/or conveyed by means of a conveyor device. The unit processing the reformats is an auxiliary power unit of a motor vehicle and/or a burner for heating-up a system component.
