Fuel cell system

A fuel cell system comprises a fuel cell having an anode flow path extending through the fuel cell between an anode inlet and an anode outlet, and a cathode flow path extending through the fuel cell between a cathode inlet and a cathode outlet. An anode purge valve is coupled to the anode outlet and...

description A fuel cell system comprises a fuel cell having an anode flow path extending through the fuel cell between an anode inlet and an anode outlet, and a cathode flow path extending through the fuel cell between a cathode inlet and a cathode outlet. An anode purge valve is coupled to the anode outlet and has an outlet coupled to the cathode inlet. A purge valve controller is configured to effect a purge cycle by opening and closing the anode purge valve and to monitor a fuel cell voltage profile during the purge cycle to determine an operational state of the anode purge valve. A fuel cell voltage drop during a period following a command signal instructing opening of the anode purge valve is used to indicate successful start of a purge cycle. A fuel cell voltage rise during a period following a command signal instructing closing of the anode purge valve is used to indicate a successful end to a purge cycle. 种燃料电池系统包括燃料电池，其具有阳极流动路径以及阴极流动路径，该阳极流动路径在阳极入口与阳极出口之间延伸通过所述燃料电池，该阴极流动路径在阴极入口与阴极出口之间延伸通过所述燃料电池。阳极冲洗阀联接到所述阳极出口并具有
