An electrochemical cell arrangement using a bipolar plate is disclosed, wherein the bipolar plates are formed from single or multiple sheets of metal foil, preferably titanium, embossed with the fluid fields. The bipolar plate, which forms the oxygen, hydrogen, and coolant passages and acts as a separator between adjacent cells of a cell stack, is lightweight, small compared to conventional bipolar plates, ductile, inexpensive, and easy to produce. |
