Während einiger Vorgänge wird ein Brennstoffzellensystem eines FCEV in einem Spannungsunterdrückungsmodus betrieben, wenn sich das FCEV in der Parkstellung befindet und der Leistungsbedarf niedrig ist, um den Verschleiß des Brennstoffzellensystems zu reduzieren. Im Spannungsunterdrückungsmodus kann sich jedoch aufgrund des geringen Stroms von Reaktantengasen, die in der Regel das Wasser entfernen, flüssiges Wasser in dem Brennstoffzellensystem ansammeln. Wenn das FCEV den Parkzustand verlässt und eine hohe Beschleunigung erfährt, kann das Wasser den Reaktantenstrom hemmen.

The fuel cell system comprises at least one fuel cell stack (11) having a plurality of fuel cells, as well as a cell voltage monitoring system (20). During a start-up process of the fuel cell system, in particular at cold ambient temperatures, open-circuit voltages of individual fuel cells are detected by means of the cell voltage monitoring system (20), and a reference value is determined on the basis of the detected open-circuit voltages, in particular a mean value of all open-circuit voltages. It is then determined whether a detected open-circuit voltage of at least one of the fuel cells deviates from the reference value, in particular whether the open-circuit voltage is lower than the mean value. If a deviation is detected, an impending polarity reversal of the at least one fuel cell is diagnosed accordingly, which would be expected to occur if an electrical load intended for operation were applied to the fuel cell stack (20). This creates the possibility of optionally modifying, delaying, or, if necessary, even completely preventing the connection of an electrical load.

Described herein are gas diffusion anodes, electrolytic systems comprising such anodes, as well as methods of using such systems. A gas diffusion anode comprises a current collector, an anode porous base, an anode catalyst layer, and an anode-liquid interfacing layer. During the operation, the anode gas chamber receives hydrogen gas, which flows through the current collector into the anode porous base. The anode porous base provides uniform distribution of the hydrogen gas as well as uniform current density. The anode catalyst layer converts the hydrogen gas into protons and returns electrons, through the anode porous base, to the current collector. Protons are transported by the anode-liquid interfacing layer to an anolyte. This layer also blocks the anolyte from contacting the anode catalyst layer. The anode porous base, anode catalyst layer, and anode-liquid interfacing layer help to prevent the migration of the anolyte into an anode gas chamber.
