Dosing of water or hydrocarbon containing medium into a partial oxidation stage (POX) in a gas generation system of a motor vehicle fuel cell, whereby the dosing pipeline has a pressure relief valve to ensure homogeneous operation

摘要

Device for dosing of a fluid medium into a component has one or more pumps and a dosing pipeline between the pump and the component. Within the pipeline or the component, temperatures above the boiling point of the medium may occur and a pressure release valve (12) is accordingly placed in the dosing line (5) which opens into a overflow pipeline (13) above a certain pressure.
