Abstract
This invention belongs to the field of fuel cell technology, specifically relating to a method for preparing an anode catalyst layer for an ethanol fuel cell based on a Pd@Ni / Co3O4 composite material. The method includes the following steps: adding a metal salt solution composed of cobalt and nickel salts to a 2-methylimidazole solution and allowing it to stand for aging to obtain Ni / ZIF-67; calcining the Ni / ZIF-67 to obtain a porous Ni / Co3O4 material; dispersing the porous Ni / Co3O4 material in a Pd(Ac)2 solution, stirring and reacting, and drying to obtain the Pd@Ni / Co3O4 composite material; dispersing the Pd@Ni / Co3O4 composite material and single-walled carbon nanotubes in a solvent to obtain a catalyst slurry; and then coating the catalyst slurry onto the surface of carbon cloth to obtain the anode catalyst layer. This process is simple, low-cost, and suitable for the large-scale preparation of anode catalyst layers for ethanol fuel cells.
