Device for the sealing of a block formed of a pile of plates, such as a block of a fuel cell, while maintaining free passageways between these plates |
摘要 |
Process for sealing a block formed of a piling of spaced plates while preserving passageways between several plates and on at least one edge of the block, comprising inserting into the intervals between said plates the teeth of a comb adapted to substantially fill these intervals, casting a solidifiable material on said edge and withdrawing the comb after the casting operation, said teeth being made of a non-adhesive material with respect to the solidifiable material of the casting. This process and the resulting sealed blocks are particularly useful in the field of fuel cells.
