•Anode flooding is a critical issue of PEM-based electrochemical hydrogen pump.•Coating the gas diffusion media with Ag-HDFT renders it super-hydrophobic.•The coating effectively eliminated the anode flooding issue. Anode flooding is a critical issue in proton exchange membrane (PEM)-based electroch...
