    摘要: A fuel cell includes a water transport plate providing a water flow field. The water flow field permits a flow of water having an entrained gas. A vent is in fluid communication with the water flow field. At least some of the gas is released from fuel cell by opening a vent. In a disclosed example, a valve is opened in response to conditions indicative of an undesired amount of gas. For example, the valve is actuated in response to a signal from a water level sensor. In another example, the valve is opened based upon a schedule.

    摘要: A circulation pipe for a coolant is connected to a fuel cell. A pump and a heat exchanger are connected to the circulation pipe. A bypass pipe is connected in parallel with the pump. An ion exchanger is connected to the bypass pipe. An electronic cooling device is connected to the bypass pipe on an upstream side of the ion exchanger. The coolant, which is supplied to the ion exchanger, is cooled by the electronic cooling device to a predetermined temperature, so that the ion-exchange resins are prevented from being abnormally heated by the coolant.

    摘要: Disclosed are a device and method for detecting the coolant level in a thermal management system for a fuel cell vehicle, which can accurately and rapidly detect the lack of coolant using a detection value of a pressure sensor. That is, the present invention provides a device and method for detecting the coolant level in a thermal management system for a fuel cell vehicle, which can accurately and rapidly monitor the lack of coolant by calculating in real time the lack of coolant based on a change in slope value and a change in amplitude of a detection value of a pressure sensor according to the flow of coolant while the pressure sensor is mounted in a coolant line connected to an inlet of a fuel cell stack and a reservoir is connected to a pressure cap of a radiator.

    摘要: An object of the invention is to provide a fuel cell system capable of improving accuracy of water content estimation during a standstill.A fuel cell system includes a fuel cell having a plurality of single cells laminated together and an estimating unit for estimating residual water content distributions in a fuel gas flow channel and an oxidation gas flow channel and a moisture content distribution in an electrolyte membrane in a cell plane of each single cell while taking into consideration water transfer that occurs between an anode electrode and a cathode electrode via the electrolyte membrane. The estimating unit estimates a residual water content of the fuel gas flow channel during a standstill from a shutdown to a restart of the fuel cell system based on temperature information on each single cell acquired during the standstill. In addition, the fuel cell system is capable of executing a scavenging process on the fuel gas flow channel when the residual water content of the fuel gas flow channel estimated during the standstill exceeds a predetermined threshold.
