    Abstract: A method for coating an ion-exchange membrane with a catalyst layer by first heating a surface of the membrane to thereby soften the surface, followed by deposition of a catalyst composition and compaction into the ion-exchange membrane to produce a catalyst-coated membrane. Heating of the ion-exchange membrane may be at a temperature between 20null C. and 50null C., typically between 30null C. and 40null C., above the glass transition temperature of the dry ion-exchange membrane. In one embodiment, the catalyst composition is fluidized in a fluidized bed reactor prior to being deposited on the membrane surface. A system for coating the ion-exchange membrane is also provided. The catalyst-coated membrane is particularly useful in electrochemical fuel cells.

    Abstract: The electrochemical performance of an ion-exchange membrane in a fuel cell system may be improved by impregnating therein a perfluoroamine. The amine may be primary, secondary or tertiary. Further, the amine is preferably water insoluble or only slightly water soluble. For example, the amine may be perfluorotriamylamine or perfluorotributylamine. Use of such a membrane system within a fuel cell may allow high or low temperature operation (i.e. at temperatures greater than 100null C. or less than 0null C.) as well as operation at low relative humidity.

    Abstract: Certain fuel cells (e.g., solid polymer electrolyte fuel cells) may temporarily exhibit below normal performance after initial manufacture or after prolonged storage. While normal performance levels may be obtained after operating such fuel cells for a suitable time period, this process can take of order of days to fully complete. However, various conditioning and/or maintenance techniques are disclosed that provide for normal performance levels without the need for a lengthy initial operating period.
