Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] see figure 1 . The fuel cell 10 of the preferred embodiment of the present invention comprises gas diffusion layers 5 and 9, positive pole 6, negative pole 8, proton exchange membrane 7, wherein, proton exchange membrane 7 is positioned between positive pole 6 and negative pole 8, gas diffusion layer 5 and 9 Then, they are respectively located outside the positive electrode 6 and the negative electrode 8 .

[0019] Please also see figure 2 . Both the positive electrode 6 and the negative electrode 8 are composed of a catalyst 4. The catalyst 4 includes carbon nanospheres 1 and catalyst metal 2. The catalyst metal 2 is filled in the carbon nanospheres 1. In this embodiment, the catalyst metal 2 is platinum metal.

[0020] Nano carbon sphere 1 is a polyhedral carbon cluster composed of multilayer graphite layers with a sphere-in-sphere structure. It...

Abstract

This invention provides a catalyst for fuel battery including nm carbon spheres and catalyst metal filled in the nm carbon spheres. The further improvement is that said catalyst also includes dewatered polymers connected to the corner and bend part of nm carbon spheres. This invention also provides a fuel battery including a gas diffusion layer, positive, negative and proton exchange film, the positive and negative are formed by said catalyst with stable state and high dispersion and reduced toxicity. Said battery can get rather high catalyst active area and reduce the potential drop and prevent toxicity.

Description

【Technical field】 [0001] The invention relates to a catalyst for a fuel cell and a fuel cell thereof, in particular to a catalyst for a fuel cell with reduced poisoning and high dispersion and a fuel cell thereof. 【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 wh...
