Patent ID: 7122273

Claim:
Two-pole plate forming the first pole plate of a basic element of a fuel cell and the second pole plate of a second basic element adjacent to the first basic element in the same fuel cell, comprising: a flat central skeleton composed of two thin plates ( 30 ), fixed parallel to each other at a spacing by gluing and using blocks ( 32 , 34 , 35 ), and thus delimiting a first space to enable circulation of coolant; two supply plates ( 20 I, 20 S) made of composite conducting material placed on each side of the flat central skeleton except on the edge, and on each of which at least one fuel or oxidant circulation channel ( 21 S, 21 I) is formed; and a frame ( 11 ) made of a dielectric material placed on each side of the flat central skeleton and around the supply plates ( 20 I, 20 S); manifold holes ( 15 , 16 ) being provided around the periphery of the flat central skeleton and the frame ( 11 ) to form manifolds for fuel and oxidant, and supply channels ( 33 ), being provided between these thin plates ( 30 ) to connect these manifold holes ( 15 , 16 ) to the circulation channels ( 21 S, 21 I).
