Method for making an assembly of base elements for a fuel cell substrate

摘要

The method enables manufacture of assemblies of several basic elements for a stage of a fuel cell, without making use of expensive machining or difficult mechanical assemblies. The method consists of using a basic porous matrix (20) in which an ionic conductor (24) surrounded by an anode (22) and an electrode (23) is deposited, for each basic element, and the assembly is isolated by a peripheral seal (21) and pairs of isolating walls (25). Electronic conductors (26) connect the anode (22) of a basic element to the cathode (23) of the basic element adjacent to it. This method may be applied to all fuel cells.
