description The invention relates to a high-platinum-loading-capacity platinum/carbon catalyst for a fuel cell and a preparation method of the high-platinum-loading-capacity platinum/carbon catalyst, and belongs to the technical field of electrochemistry, and the catalyst comprises the following components in percentage by mass: 30-70% of carrier carbon and 30-70% of active component platinum. According to the method, an ethanol solution of sodium borohydride is adopted as a reducing agent, and the high-platinum-loading-capacity platinum/carbon catalyst for the fuel cell is obtained through two-stage synthesis and precise speed control. The prepared high-platinum-loading-capacity platinum/carbon catalyst has the advantages of high catalytic activity, high chemical stability, good dispersity and the like, and the further development of fuel cells is promoted. 本发明涉及一种燃料电池用高铂负载量铂/碳催化剂及其制备方法，属于电化学技术领域，该催化剂的质量百分比组成为：载体碳：30％～70％，活性组分铂：30～70％。本发明的方法采用硼氢化钠的乙醇溶液为还原剂，通过两段合成、精准控速，得到燃料电池用高铂负载量铂/碳催化剂。本发明制备的高铂负载量铂/碳催化剂具有催化活性高和化学稳定性高、分
