Claims

[Claims for Utility Model Registration] (1) A plate formed of an extruded metal material and having a large number of through holes inside, used in a fuel cell consisting of a stack of multiple unit cells and a cooling plate. a first joining member that is joined to one end surface of the plate-like member, covers one opening of the through-hole, and has a first connecting hole therein that communicates with the plurality of through-holes; a second joining member that is joined to the other end surface of the plate-like member, covers the other opening of the through hole, and has a second connecting hole therein that communicates with the plurality of through holes; a fuel cell stack comprising: cooling plate. (2) Claim (1) characterized in that the first and second joining members are made of extruded metal material.
) The fuel cell laminate cooling plate described in ).
