Abstract
Official abstract text for this publication.
A method for manufacturing a catalyst for fuel cell includes: providing or receiving magnesium porphyrin-containing powder; mixing the magnesium porphyrin-containing powder with a carbon-containing carrier powder to form a first mixture, and performing a thermal treatment to pyrolyze the first mixture to form the catalyst for fuel cell. A catalyst for fuel cell is also provided herein.
First claim
Opening claim text (preview).
What is claimed is: 1. A catalyst for fuel cell comprising a magnesium porphyrin and a carbon carrier, and the catalyst further comprising at least six elements comprising oxygen, carbon, nitrogen, sulfur, silicon and magnesium, wherein a molar percentage of oxygen in the six elements is about 31.3 to about 37.3 mol %, a molar percentage of carbon in the six elements is about 40.04 to about 47.61 mol %, a molar percentage of nitrogen in the six elements is about 13.7 to about 16.8 mol %, a molar percentage of sulfur in the six elements is about 2.62 to about 4.34 mol %, a molar percentage of silicon in the six elements is about 1.38 to about 3.1 mol %, and a molar percentage of magnesium in the six elements is about 1.75 to about 1.87 mol %. 2. The catalyst of claim 1 , wherein the catalyst comprises quaternary-type nitrogen, pyrrole-type nitrogen and cyanide, and when a total molar percentage of the quaternary-type nitrogen, the pyrrole-type nitrogen and the cyanide is regarded as 100%, a molar percentage of the quaternary-type nitrogen is about 15.2 to about 36.1 mol %, a molar percentage of the pyrrole-type nitrogen is about 41.2 to about 68.2 mol %, and a molar percentage of the cyanide is about 18.2 to about 22.7 mol %. 3. The catalyst of claim 1 , wherein the catalyst comprises a —C—S—C— group and —C—SO x —C— groups, and when a total molar percentage of the —C—S—C— group and —C—SO x —C— groups is regarded as 100%, a molar percentage of the —C—S—C— group is about 69.4 to about 100 mol %, and a molar percentage of —C—SO x —C— groups is about 0 to about 30.6 mol %, wherein x is an integer ranged from 0 to 6.
