| 20080292934 | POROUS COMPOSITE PRODUCT FOR THE PRODUCTION OF A CATALYTIC LAYER, IN PARTICULAR IN FUEL CELL ELECTRODES - A composite product is for an electrode of a fuel cell including a catalyst, an electrically conductive phase which supports such catalyst, a protonically conductive phase, and a porous phase. At least the contact between the catalyst and the electrically and protonically conductive phases, and preferably also the contact of the porous phase with the catalyst and with the electrically and protonically conductive phases, is improved or maximized. Each of the phases is individually continuous, and such phases are continuous with each other. | 11-27-2008 |
| 20080299437 | POLYELECTROLYTE MEMBRANE FOR ELECTROCHEMICAL APPLICATIONS, IN PARTICULAR FOR FUEL CELLS - A polyelectrolyte membrane may include at least one styrene polymer or copolymer having a syndiotactic configuration and having sulfonic groups. The at least one styrene polymer or copolymer may be made in the form of a film in clathrate form. The film may include less than about 0.1% sulfonate groups of —SO | 12-04-2008 |
| 20090136820 | PROTON EXCHANGE MEMBRANE AND MEMBRANE-ELECTRODE ASSEMBLY (MEA), METHOD FOR THEIR PRODUCTION AND FUEL CELL USING SAID MEMBRANE OR ASSEMBLY - A proton exchange membrane for electrolyte cells includes a polyelectrolyte polymer membrane comprising a sulfonated copolymer based on the following formula (I): | 05-28-2009 |
| 20090196984 | ELECTROCATALYTIC POLYMER-BASED POWDER, METHOD OF PRODUCTION AND USE THEREOF - An electrocatalytic polymer-based powder has particles of at least one electronically conductive polymer species in which particles are dispersed of at least one catalytic redox species, in which the particles of the polymer species and of the catalytic species are of nanometric dimension. | 08-06-2009 |
