Wasserabscheidevorrichtung für eine Brennstoffzelle mit beweglicher Ventileinrichtung

Various embodiments of the teachings herein include a water separation device for a fuel cell. An example includes: a separator for separating water from an aqueous gas mixture discharged from the fuel cell; a container defining a collection volume to collect the water from the separator; and a freeze protector including a displaceable valve coupled to the collection volume. When the water in the collection volume freezes, the valve moves in the direction of a freeze position enlarging the collection volume. When frozen water in the collection volume melts, the valve moves back in the direction of a melt position reducing the collection volume.
