Accelerated diffusion of hydrogen was observed at room temperature in polycrystalline nickel samples with the electrochemical permeation technique. A larger hydrogen flux was measured in annealed samples with 25 pm grain size whereas faster hydrogen diffusion was observed at the early stage of the p
