Abstract
The invention is a freeze tolerant fuel cell power plant that includes at least one fuel cell; a coolant loop having a coolant circulating device that directs a water coolant through a water transport plate within the fuel cell; and a water displacement system having a freeze tolerant accumulator that contains a water immiscible fluid and water coolant. The water displacement system also includes a water immiscible fluid pump, heater and displacement valves for directing the water immiscible fluid to flow from the accumulator into the coolant loop; for directing the water coolant in the coolant loop to flow into the accumulator; and, for directing heated water immiscible fluid to flow from the accumulator into the coolant loop and back into the accumulator.
