Abstract

The invention discloses a catalyst for a hydrogen fuel cell. The catalyst is prepared from the following raw materials in parts by weight: 16-20 parts of iron oxide, 2-5 parts of caesium hydroxide, 135-140 parts of carbon black, 8-12 parts of chitosan oligosaccharide, 1-2 parts of ferric citrate, 0.4-0.8 part of trimethylol propane, 0.2-0.5 part of hexamethylenetetramine, 0.04-0.07 part of seconary alkane sulphonate sodium and 4-5 parts of urea. The invention also discloses a method for preparing a high-performance catalyst for the hydrogen fuel cell. The catalyst for the hydrogen fuel cell prepared by the scheme of the invention has better catalytic performance for the oxidation of hydrogen, since no precious metal platinum is used, the cost of the catalyst for the hydrogen fuel cell canbe reduced, and thus the cost of the hydrogen fuel cell can be reduced, and an important market value can be achieved.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cells, in particular to a catalyst for hydrogen fuel cells and a preparation method thereof. Background technique [0002] A fuel cell is a power generating device that directly converts the chemical energy present in fuel and oxidant into electrical energy. Fuel and air are sent separately to the fuel cell, and electricity is miraculously produced. It looks like a battery with positive and negative electrodes and electrolytes from the outside, but in essence it cannot "storage electricity" but a "power plant". However, it requires electrodes and electrolytes and redox reactions to generate electricity. Fuel cells are recognized as the preferred clean and efficient power generation technology in the 21st century. Its research and development has become a research hotspot in the international energy field, and will promote the rapid development of the entire electric vehicle, submarine and ...
