METHOD FOR COATING BOTH SIDES OF A MEMBRANE-ELECTRODE ASSEMBLY WITH A CATALYST |
摘要 |
The invention relates to a single-step method for coating both sides of a membrane-electrode assembly with a catalyst. According to the inventive method, two precursor layers are contacted with a membrane and the catalyst is alternately electrochemically deposited on the electrodes. Specific adsorption layers are produced in a controlled manner during the method on the counter-electrode by controlling the pulse width or by adding agents that form an adsorbate, thereby regularly preventing the membrane-electrode assembly from damages, such as for example due to carbon consumption. |
