Tip‐top electrode : A conductive cantilever tip that acts as an electrode permits proton conductivity measurements through a Nafion membrane with a resolution of ≈10 nm. The figure shows a spatially resolved electrochemical atomic force microscopy (EC‐AFM) image of the proton conductivity of a Nafion 112 membrane, recorded at an applied voltage of −1.55 V and a relative humidity of 35 %.
