Drive system for a hydrogen-powered vehicle with quick-change function and method

Abstract

The invention relates to a drive system (10) for a hydrogen-powered motor vehicle (12), comprising a fuel cell (14) or a hydrogen drive / hydrogen engine and at least one hydrogen storage device (16), by means of which, with the integration of hydrogen generation, the drive of the motor vehicle (12) can be controlled, wherein, for the purpose of conveying hydrogen to the fuel cell (14) or the hydrogen drive / hydrogen engine, the fuel cell (14) or the hydrogen drive / hydrogen engine and the hydrogen storage device (16) are fluidically connected to one another, wherein a quick-release clamping device (18) with a valve element (20) is arranged between the hydrogen storage device (16) and the fuel cell (14) or the hydrogen drive / hydrogen engine. The invention further relates to a method for operating such a drive system (10).

Claims
