| 摘要 |
The invention relates to a method for preparing a fuel cell electrode membrane assembly by means of electrodeposition, which includes the following steps: depositing a composition containing at least one transition metal precursor and electronically conductive particles, on a main surface of a proton exchange membrane; drying the deposit; positioning the proton exchange membrane in an electrodeposition cell; reducing the transition metal precursor to transition metal particles having a degree of oxidation equal to 0, by causing an electric current to flow in the electrodeposition cell; and obtaining an electrode membrane assembly, the proton exchange membrane of which includes a main surface containing transition metal particles having a degree of oxidation equal to 0. |
