摘要： A freeze protection method for a fuel cell system is disclosed. The fuel cell system includes an evaporative cooler device equipped for cooling a heat exchanger of a fuel cell device of the fuel cell system having a feed line, through which during the operation of the fuel cell system, water is pumped to a sprinkling device of the evaporative cooler device and by way of the sprinkling device, the water is applied onto the heat exchanger equipped for temperature-controlling a fuel cell stack of the fuel cell device. The method includes blowing out the evaporative cooler device as part of a deactivation method of the fuel cell system.

摘要： A heat exchanger for a fuel cell is disclosed. The heat exchanger includes at least two tube bodies that are arranged at a distance from one another and are in each case structured so that a fluid can flow through internally and so that air can flow around externally. A water channel, through which water can flow fluidically separated from the fluid, is arranged in or on at least one tube body. At least one opening, via which the water channel communicates fluidically with an external environment of the at least one tube body, is provided on the at least one tube body. The at least one opening is arranged in the at least one tube body so that at least one of the tube bodies can be wetter with water, which is guided through the water channel and escapes the water channel through the at least one opening.

摘要： The present invention relates to a fuel cell device (1) having a fuel cell (2) which, during operation, emits water as a product of cold combustion; a supply air path (3) leading to the fuel cell (2) for a cathode supply air flow (5), which defines a supply air flow direction (4), the cathode supply air flow coming from water-containing supply air supplied to the fuel cell (2); and an exhaust air path (7)leading away from the fuel cell (2), for a cathode exhaust air flow (9), which defines an exhaust air flow direction (8), the cathode exhaust air flow coming from water-containing exhaust air flowing out of the fuel cell (2). The supply air path (3) and the exhaust air path (7) are routed through a humidifier (10) of the fuel cell device (1), which humidifier communicates fluidically with the supply air and the exhaust air, to humidify the supply air and dehumidifying the exhaust air. The exhaust air path (7) is also routed through a water separator (11) of the fuel cell device (1), which water separator communicates fluidically with the exhaust air, for removing water from the exhaust air and for providing this water as evaporation water. The fuel cell device (1) also has a heat exchanger (12) for cooling the fuel cell (2), which heat exchanger has an evaporative cooler (13) for cooling the heat exchanger (12). It is essential that the evaporative cooler (13) is assigned to the water separator (11) in fluidic communication and that it is supplied with evaporation water by same.

摘要： An intercooler may include an air-outlet tank, a condensate collector for collecting condensate separated off the intercooler, and a condensate line connected to the condensate collector via an entrance and that opens out into the air-outlet tank via an exit. There may be a pressure difference between the entrance and the exit of the condensate line during operation of the intercooler, and said pressure difference may allow differential-pressure-induced discharge of condensate from the condensate collector via the condensate line.

摘要： A thermal management system for a vehicle may include a refrigerant circuit in which a refrigerant circulates, as well as a heating circuit, a first coolant circuit configured for a temperature control of a drive device of the vehicle, and a second coolant circuit configured for a temperature control of an electrical store of the vehicle in which a coolant circulates. The system may further include a chiller incorporated in the refrigerant circuit and a chiller guide fluidically separate from the refrigerant circuit. The chiller guide may have a chiller path configured to conduct the coolant and which extends through the chiller, and may have a bypass path configured to conduct the coolant and which circumvents the chiller. The system may additionally include a chiller valve device configured to selectively fluidically connect the first coolant circuit and the second coolant circuit to the chiller path and the bypass path.
