| titleOfInvention | Electrocatalytic material, preparation method and proton exchange membrane fuel cell |
| abstract | The invention discloses a preparation method of a platinum-iron alloy catalyst for a proton exchange membrane fuel cell, which comprises the following steps: the high molecular organic matter is used as an initiator, and is subjected to flocculation reaction with iron ions in a solution, and phase separation is carried out to generate a uniformly dispersed Pt-Fe micelle precursor, so that the high-performance nanoparticle catalyst is prepared, and the catalyst is doped and modified by adopting an organic nitrogen source, so that the catalytic performance is improved. Compared with the prior art, the method provided by the invention adopts a simple and feasible method to improve the load distribution and the particle size uniformity of the catalyst particles on the carbon substrate, and realizes the purposes of reducing the production cost of the catalyst and improving the yield. |
