Abstract
Modified ion-conducting membranes (10), and a method for making the same, which increases the membrane (10) surface area, and, optionally, incorporates mono- and multi-metal ion-containing catalysts for both fuel consumption catalysis in fuel cells as well as catalysis of reactions to ameliorate the effects of CO and other impurities in fuel cells. The membranes (10) modified by these methods can fin application in catalysis and transport applications.
Claims9
A method for forming an ion conducting polymer membrane having a deformed surface area exceeding the membrane's cross-sectional area by at least 20%, said method comprising the steps of:
- providing an ion conducting polymer membrane (10);
- at least partially dehydrating said membrane (10);
- and
- applying a voltage across said membrane (10) sufficient to generate surface deformation on said membrane.
