Low temperature fuel cell and method for operating the same

The low-temperature fuel cell stack has at least two fuel cells with an anode (1), a cathode (2) and an electrolyte membrane (5) between them. The method involves transferring heat generated on the cathode side of a first fuel cell to the fuel in the anode chamber of a second adjacent fuel cell so that the fuel is at least partly evaporated. An independent claim is also included for the following: (a) a low-temperature fuel cell stack.
