摘要

The fuel cell system has a fuel-cell stack (10), whose fuel cells are connected with an air inlet pipe (16) and with an air outlet pipe (24) by an end plate (14) or a distribution plate. Locking units (32,34) prevent air supply through the air inlet pipe and the air outlet pipe. Each locking unit is arranged directly on or in the end plate or distribution plate, which is connected with the air inlet pipe or with the air outlet pipe.
