Fuel cell power plant operating system and method for use in sub-freezing ambient conditions
Abstract:
The fuel cell power plant operating system (10) includes an on/off switching device by-pass circuit (60) to sustain operation of a fuel cell (12) whenever the fuel cell (12) on/off switching device (58) is turned off while a fuel cell operating temperature is below a predetermined freeze-safe operating temperature. The by-pass circuit (60) operates the fuel cell (12) until the fuel cell (12) temperature reaches or exceeds the freeze-safe temperature to thereby prevent fuel cell (12) product water from becoming ice in and adjacent fuel cell catalysts (26, 40).
Abstract(Chinese):

燃料电池发电厂操作系统（10）包括每当燃料电池（12）通/断切换装置（58）为...时，燃料电池（12）的运行来维持燃料电池（12）的操作的开关装置旁通电路（60） 当燃料电池工作温度低于预定的冷冻安全工作温度时关闭。 旁路回路（60）操作燃料电池（12），直到燃料电池（12）温度达到或超过冷冻安全温度，从而防止燃料电池（12）产生的水在燃料电池催化剂和邻近的燃料电池催化剂 （26，40）。
