Abstract
A high molecular weight direct antifreeze cooled fuel cellincludes an electrolytesecured between an anode catalystand a cathode catalysta porous anode substratesecured in direct fluid communication with and supporting the anode catalysta porous wetproofed cathode substratesecured in direct fluid communication with and supporting the cathode catalysta porous water transport platesecured in direct fluid communication with the porous cathode substrateand, a high molecular weight direct antifreeze solution passing through the porous water transport plateto cool and remove product water from the fuel cellThe high molecular weight direct antifreeze solution preferably includes polyethylene glycol having a molecular weight ranging from 200 to 8,000 AMU. The direct antifreeze solution does not leave the water transport platein significant quantities to poison the catalysts.
