| 摘要 |
<p>The invention is a freeze tolerant fuel cell power plant (200) that includes at least one fuel cell (12') and a water transport plate (50') secured within the fuel cell (12') having a coolant inlet (202) and a coolant outlet (204) that direct a water coolant through the plate (50'). A suction water displacement system (206) includes a freeze tolerant accumulator (78') secured to the coolant inlet (202) and a vacuum separator (210) secured to the coolant outlet (204) having a suction generating eductor (212) secured to the separator (210). Control valves (222), (224) and a coolant pump (214) selectively direct either the water coolant, heated or un-heated water immiscible fluid to cycle from the accumulator (78'), through the coolant inlet (202), water transport plate (50'), coolant outlet (204), vacuum separator (210) and back to the accumulator (78') in order to permit operation and storage of the plant (200) in sub-freezing ambient temperatures.</p> |
