Practical catalysts for low-temperature fuel cells are generally nanoscale in size and commonly produced or deposited on surfaces with a large surface area. In proton exchange membrane fuel cells, platinum (Pt) is the catalyst that is most frequently utilised for both the cathode and the anode (PEMFCs). Combination catalyst systems, such as Pt nanoparticles supported on Au or Pt alloy catalysts, as well as Pt-skin catalysts produced in conjunction with the iron group metals, have drawn interest in the cathode instance. Bi-metallic catalysts are frequently used for the anode, unless the fuel is pure H2. For both methanol and reformated fuel cells, Pt-Ru is the most modern catalyst. Pt/MoOx and Pt/Sn are two more anode catalysts that are thought to hold promise for the latter.
