CATALYST, PRODUCTION PROCESS THEREFOR, AND USE THEREOF |
摘要 |
The invention provides catalysts that are not corroded in acidic electrolytes or at high potential and have excellent durability and high oxygen reducing ability. The catalyst includes a metal element M, carbon, nitrogen and oxygen, wherein the catalyst shows peaks at 1340 cm−1 to 1365 cm−1 and at 1580 cm−1 to 1610 cm−1 as analyzed by Raman spectroscopy and the metal element M is one selected from titanium, iron, niobium, zirconium and tantalum. The catalysts of the invention are stable and are not corroded in acidic electrolytes or at high potential, have high oxygen reducing ability and are inexpensive compared to platinum. Fuel cells having the catalysts are therefore relatively inexpensive and have high performance.
