Ultrathin Ultralow‐Platinum Catalyst Coated Membrane for Proton Exchange Membrane Fuel Cells (Small 21/2023)

Proton Exchange Membrane Fuel Cells In article number 2207155, Huiyuan Liu, Yujiang Song, and co-workers construct ultrathin ultralow-Pt integrated catalyst coated membrane by proton-initiated regioselective nucleation and growth of Pt/Pd catalyst layer on membrane. The highly active ultrathin catalyst layer greatly facilitates mass transfer and enhances the peak mass specific power density up to 59.9 W mgPt, Cathode−1 for proton exchange membrane fuel cell.
