ABSTRACT:
The present invention provides a fuel efficient membrane electrode assembly that substantially resists methanol from “crossing over” by sealing the anode diffusion layer and catalyst layer, and by preventing fluids from passing across at least a portion of the membrane electrolyte. The efficiency of the fuel cell is maintained because essentially all of the fuel is reacted on the catalyst layers creating electricity, which is transferred to the fuel cell load. The temperature of the fuel cell is also maintained as the uncatalyzed reaction that produces heat is prevented.
