  "textContent": "The present invention discloses a platinum-carbon catalyst and preparation process and use thereof and a hydrogen fuel cell with the platinum-carbon catalyst. A platinum-carbon catalyst contains a carbonaceous support and metallic platinum particles supported on the carbonaceous support. At least 50% of metallic platinum particles have a contact angle relative to the carbonaceous support of 70° or less. According to the platinum-carbon catalyst of the present invention, the metallic platinum particles have relatively good dispersion on the carbonaceous support, the catalyst has highly uniform cluster particles, and the metallic platinum and the carbonaceous support have a strong interaction each other, showing an improved electrochemical active surface area and a superior electrochemical stability. The process for preparing the platinum-carbon catalyst according to the present invention has the characteristics of batch repeatability and easy industrial scale-up, and can realize batch production of the platinum carbon catalyst.",
