Abstract:
1. A fuel cell system comprising: (a) at least one fuel cell, said at least one fuel cell comprising an anode, a cathode, an electrolyte separating said anode and said cathode, an oxidant gas inlet in fluid communication with said cathode and an excess oxidant gas outlet in fluid communication with said cathode; (b) a plurality of gas/water separator tanks, each of the gas/water separator tanks being adapted for fluid connection to said oxidant gas inlet and to said excess oxidant gas outlet of said at least one fuel cell and also being adapted for fluid connection to one another, at least one of said gas/water separator tanks containing a quantity of water, at least another of said gas/water separator tanks containing a quantity of oxidant gas; and (c) pump means for transferring water from the at least one gas/water separator tank containing a quantity of water to the at least another gas/water separator tank containing a quantity of oxidant gas so as to displace oxidant gas from the at least another gas/water separator tank containing a quantity of oxidant gas, whereby the displaced oxidant gas is conducted to the oxidant gas inlet.
