ABSTRACT:
A process for the selective sealing of at least one end of a cellular module, the latter having rows of parallel channels for carrying at least two different fluids. The process consists of depositing a tight material on the end of the module to be sealed. Deposition is preceded by a preblocking operation using a material in the channels to be sealed which does not contribute to the actual sealing, but which serves as a mechanical support during the deposition of the sealing material, whereby only those channels having the preblocking material are sealed.
