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 find application in catalysis and transport applications.
Claims12
An ion conducting polymer membrane (10) that can be be placed between an associated anode and an associated cathode, the ion conducting polymer membrane exhibiting surface deformation such that at least one deformed surface area of said membrane exceeds a subtended area of an unmodified membrane surface by at least 20% and further comprising a catalyst layer (20) deposited on, inside, or on and inside the surface of said membrane.
