McElroy, J F

A fuel cell comprising an anode containing a catalyst, an ion exchange membrane electrolyte, a cathode and wet proofing means is described wherein the improvement comprises: (a) aspirator means to form a liquid water mist from supplied liquid water; (b) means for controlling the amount of liquid water supplied to the anode; and (c) a desiccant material within the anode to transport the liquid water mist to the ion exchange membrane and to prevent local area flooding; wherein fuel cell cooling is effectuated by the evaporation of sufficient liquid water from the cathode through the wet proofing means so as to eliminate the need for a separate cooling compartment.
