ABSTRACT:
In a fuel cell assembly (1) comprising a pair of separators (11, 12) each for defining a recess (10) serving as a conduit for a fuel fluid or an oxidizer fluid, a feedthrough conductive path for connecting top and under surfaces of each separator is achieved by a second electroconductive film (36) formed on a side wall of a through-hole (33) extending through each separator (11, 12) in such a manner that the second electroconductive film (36) connects a first electroconductive film (35) constituting a top surface of a protrusion (30) provided in the recess (10) to a third electroconductive film (37) formed on a surface opposite to that formed with the recess (10).
