Fuel Cells are electrochemical devices, which produce electricity from a fuel, such as hydrogen or methanol, and an oxidant, such as oxygen. Each fuel cell is capable of providing up to 1V. To obtain higher voltages, individual fuel cells are stacked in series, usually in a bipolar manor or one on top each other, to achieve higher voltages. Fuel cells assembled on a planar surface can not be stacked one on top another. Series connections of a planar stack can be made using Beryllium Copper (BeCu) contacts between the anode and cathodes of the fuel cells.
