Abstract

A system and method are provided for managing water coolant in PEM fuel cell system's (10) coolant circuit (14). Gas-liquid separating apparatus (26) serves to efficiently transport liquid coolant containing gases, and to separate gases from the liquid coolant. The liquid coolant having the gases removed therefrom is then circulated through the liquid circuit by means of a conventional pump (24). A vacuum pump (28), such as a liquid eductor (28'), associated with the gas-liquid separating apparatus (26), serves to efficiently transport gas-phase and/or gas-liquid phase, fluids and to assist in the degasification of the liquid coolant. The eductor discharges to a separator/accumulator (30; 30') which further facilitates separation of gases from liquid coolant.
