Abstract

This invention provides a catalyst used in a fuel battery including nm carbon spheres and catalyst metal inlaid on the corner or bend part in the atomic way. Besides, it also provides a fuel battery including a gas diffusion layer, a positive, negative and proton exchange film, the positive and negative are formed by said catalyst at stable state and high dispersity. The fuel battery can get rather high active area of the catalyst which is good for battery reaction.

Description

【Technical field】 [0001] The invention relates to a fuel cell catalyst and its fuel cell, in particular to a highly dispersed fuel cell catalyst and its fuel cell. 【Background technique】 [0002] As the world's population and human activities grow, humans are often limited by the ability to supply electrical energy to support their various activities. Fuel cells provide a solution to this difficulty by generating electricity directly from chemical raw materials such as oxygen and methanol, that is, fuel cells generate electricity electrochemically, using methanol as fuel, and generating electricity after reacting with oxygen and a small amount of Heat energy, so it is also called cold combustion. Moreover, the product discharged after the fuel cell generates electricity is water (H 2 O), in line with environmental protection standards, to solve the inherent pollution problems of the direct combustion process. Especially when the equipment requires low power and long-term ...
