<p>A fuel cell power plant (10) having a fuel cell assembly (20) includes an anode (30) provided with a fuel stream, a cathode (40) provided with an oxidant stream, an ion exchange membrane oriented between said anode and said cathode, and a coolant loop (60) circulating a coolant stream in fluid communication with the fuel cell assembly. An oxidant source is utilized for supplying the fuel cell assembly with the oxidant stream at a predetermined pressure, while an accumulator (64), coolant pump (62), and pressure control valve (66) are oriented along the coolant loop lowers the coolant stream to a subambient pressure prior to the coolant stream coming into fluid communication with the fuel cell assembly.</p> |
