Abstract:
A direct antifreeze cooled fuel cell for producing electrical energy from a reducing fluid and a process oxidant stream, comprising:a. an electrolyte secured between an anode catalyst and a cathode catalyst;b. a porous anode substrate secured in direct fluid communication with the anode catalyst for passing the reducing fluid stream adjacent the anode catalyst and a wetproofed cathode support means secured in direct fluid communication with the cathode catalyst for passing the process oxidant stream adjacent the cathode catalyst;c. a porous cooler plate secured in direct fluid communication with the wetproofed cathode support means; and,d. a direct antifreeze solution passing through the porous cooler plate for cooling the fuel cell, wherein the direct antifreeze solution is an alkanetriol direct antifreeze solution.
