Abstract
The fuel cell power plant operating system () includes an on/off switching device by-pass circuit () to sustain operation of a fuel cell () whenever the fuel cell () on/off switching device () is turned off while a fuel cell operating temperature is below a predetermined freeze-safe operating temperature. The by-pass circuit () operates the fuel cell () until the fuel cell () temperature reaches or exceeds the freeze-safe temperature to thereby prevent fuel cell () product water from becoming ice in and adjacent fuel cell catalysts ().
