摘要：
The present invention provides methods for fabricating a fuel cell membrane structure that can dramatically reduce fuel crossover, thereby improving fuel cell efficiency and power output. Preferred composite membrane structures include an inorganic layer situated between the anode layer and the proton-exchange membrane. The inorganic layer can conduct protons in unhydrated form, rather than as hydronium ions, which reduces fuel crossover. Some methods of this invention include certain coating steps to effectively deposit an inorganic layer on an organic proton-exchange membrane.
