Abstract

The two-pole plate is relatively lightweight and can be manufactured quickly and easily.It consists of a skeleton made with two thin plates (30) spaced by blocks (34, 45) between which a cooling fluid circulates. The fuel and oxidant manifolds supply the circulation channels (21I) machined by water jet in supply plates (20I, 20S) made of conducting composite, through the supply channels (33). These plates are bonded with a conducting glue onto the thin plates (30).Application to fuel cells.
