Coolant velocity greater than zero everywhere within the coolant channels (78, 85) of fuel cells (38) in a fuel cell stack (37) is assured by providing a flow of gas in the coolant channels, the flow being created by gas pressure from a source (92) of pressurized gas, an oxidant reactant air pump (52), a source (75) of hydrogen-containing fuel, or the fuel outlet (47), or the outflow of a condenser (59). Positive pressure may be applied to the coolant inlet (66) or negative pressure from an eductor (97) may be applied to a gas outlet (90) of the coolant channels, or both. Using gas to induce flow within the coolant channels eliminates the need for a bubble-clearing liquid pump and reduces liquid inventory and other plumbing; this makes the fuel cell power plant more freeze tolerant. Biphase flow from the condenser, which may be a vehicle radiator (120), renders the coolant return flow more freeze tolerant. Separate cooler plates (122) may be used with a coolant management system (125).
