Abstract
The invention relates to a fuel cell system having lines for feeding hydrogen from a high-pressure hydrogen reservoir into a fuel cell assembly. The lines have a high-pressure region, a medium-pressure region, and a fuel cell operating-pressure region. The lines of the medium-pressure region are pressure-relieved upon deactivation of the fuel cell system in order to avoid hydrogen diffusing out during standstill periods of the fuel cell system, and to thus avoid the formation of explosive hydrogen/air mixtures. The invention also relates to a tank module, which is configured for pressure relieving, to a method of deactivating and re-activating the fuel cell system, to the use of a 3/2-way valve for pressure-relieving the medium-pressure region of the hydrogen lines of a fuel cell system, and to a motor vehicle having a fuel cell system or tank module.
