Abstract
The invention relates to an ion-conductive polymer membrane for a fuel cell, whereby the polymer membrane is configured from a polymer-forming hydrocarbon material and to a method for producing the same. The membrane also has a metal-containing gel which has been hydrolysed and/or condensed from a metal alkoxide starting material and which is deposited in the polymer and/or is chemically bonded to the polymer. The proportion of metal alkoxide by weight, in relation to the membrane, lies between 25% and 1%.
Claims6
A self-supporting, ion-conducting polymer membrane for a fuel cell, comprising:
- an ion-conducting polymer made of a polymer-forming hydrocarbon material;
- and
- a metal-containing gel hydrolyzed and/or condensed from a metal alkoxide, the metal-containing gel being located within the polymer and/or chemically bonded to the polymer;
- wherein the weight ratio of the metal alkoxide to the membrane is between 25% and 1%.
