Abstract Fuel cell is a kind of clean and high-efficient new energy source. It is benefit to solve the problems of energy and environment. Catalyst is an essential part of fuel cell and it influences the performance of fuel cell greatly. Different preparation methods are compared, and the influence of the property of various carbon carrier materials is also studied in this article. By measuring the performance of the catalytic oxygen electrode and analyzing the components of the catalysts，optimized preparation-method and property of the carbon carrier are found. Moreover the effects of heat-treatment and assistant metal is also studied and some theoreticed explanation is given.
Key words Fuel cell, Fuel cell catalysts, High-efficient catalysts
