Abstract
A fuel cell is provided, with an anode device having a fuel inlet, a cathode device having an oxidizing agent inlet, and a membrane arranged between the anode device and the cathode device. The fuel cell has means for self-regulating the output power of the fuel cell, which counteract a reduction in output power or regulate output power substantially independently of the fuel cell service life and operating temperature. The means can have at least one bypass diode connected electrically to the anode device and the cathode device and/or at least one fuel feed device with a self-regulating fuel feed, which has a first thermally expansible element, and/or at least one oxidizing agent feed device with a self-regulating oxidizing agent feed, which has a second thermally expansible element.
