ABSTRACT:
A component for installation in a process control apparatus, such as a fuel cell block, includes two mutually parallel plates having inner surfaces facing toward each other and outer surfaces facing away from each other. Generally flat components resting on the outer surfaces of the plates define a first chamber with one of the outer surfaces and a second chamber with the other of the outer surfaces at two sides of the component. The inner surfaces of the plates enclose a third gas-tight chamber therebetween. At least one gas-tight channel extends between the plates in the plane of the plates. The at least one gas-tight channel has an inlet end communicating with an antechamber and a discharge end to be connected to at least one of the first, second and third chambers as needed.
