Catalyst Synthesis

Practical catalysts for low-temperature fuel cells are generally in the nanometer size range and are commonly produced or deposited on high-surface-area substrates. In proton exchange membrane fuel cells, platinum is the most often utilised catalyst for both the cathode and anode (PEMFCs). In the case of the cathode, mixed catalyst systems such as Pt nanoparticles supported on Au or Pt alloy catalysts, as well as Pt-skin catalysts created in conjunction with the iron group metals, have also garnered interest. Unless the fuel is clean H2, bi-metallic catalysts are normally used in the anode instance. Modern catalysts for both reformate and methanol fuel cells use Pt-Ru. Other anode catalysts for the latter, such Pt/MoOx and Pt/Sn, are also thought to be promising. Methods for synthesis of catalyst are as follow:

- Low-temperature Chemical Precipitation

- colloidal method
