LOW-TEMPERATURE FUEL CELL STACK AND METHOD FOR OPERATING THE SAME |
摘要 |
The invention relates to a low-temperature fuel cell stack comprising a specific device for the supply of fuel. Said low-temperature fuel cell stack is characterised in that, in addition to the central fuel supply device, it comprises a supply or storage device for a liquid fuel, and a plurality of separately controllable dosing devices that lead into the central fuel supply device, especially respectively upstream of a distribution channel to the individual cells. Controllable valves, controllable piezoelectric pumps or thermally controllable supply elements are suitable as dosing devices. The invention also relates to a method for operating one such low-temperature fuel cell stack, which advantageously enables a defined concentration of fuel, or a defined humidity of the oxidation medium, to be adjusted at certain points in the fuel cell stack, especially on the inlet for the individual cells. |
