In article number 1900026 by Yanqing Ma, Lei Ma and co‐workers, ultralow platinum loading on a proton exchange membrane by e‐beam evaporation is reported. The current density reaches 500 mA cm −2 with a platinum loading of only 0.00379 mg cm −2 at 1.64 V under 80 °C while achieving a mass activity of ≈132 A mg −1 , an order of magnitude higher than traditional methods, demonstrating the economic advantages of an extremely low platinum loading.
