A new class of hydroxide exchange membranes (HEMs) is prepared by using a quaternary phosphonium‐based polymer. The membranes display desirable properties, most notably a high conductivity. A corresponding fuel cell exhibits the highest HEM fuel cell performance to date and shows a better intrinsic catalyst‐activity compared with state‐of‐the‐art proton exchange membrane fuel cells.
