Abstract
The fuel cell power plant uses stacks which are supplied with compressed air from turbocompressors. The turbines on the turbocompressors are operated with expanding cathode exhaust gases from the stack. Product water is recovered from the cathode exhaust gases after the latter pass through the turbines. Flow and/or pressure sensors are disposed downstream of the compressors to monitor the air exiting the compressor. Should the sensors detect an abnormal condition, which could result from changes in power level, or ambient temperature, then the sensors will open a normally closed valve to divert coolant steam to the turbines to provide the increased energy needed to bring the turbines up to speed.
