Based on PEM’s outstanding properties of mechanical strength and gas separation, high-pressure operation of PEM electrolyzer has been successfully realized and commercialized. However, an important problem in high-pressure PEM water electrolysis (especially under differential pressure condition, high pressure in the cathode compartment/atmospheric pressure in the anode compartment) is the permeation of hydrogen through the membrane, which affects the safety and efficiency. In this article, the research progress of hydrogen permeation in PEM electrolysis is reviewed. Firstly, the theory of permeation is introduced. Secondly, based on the relationship between permeation flux, permeability and partial pressure difference described by Fick's law, effects of temperature/pressure, hydration degree of membrane, and partial pressure difference on hydrogen permeation are reviewed. In the normal operating pressure range (< 3.5 MPa) for hydrogen production by PEM electrolysis, the diffusion coefficient and solubility are mainly affected by temperature, and the permeability increases with increasing temperature. The permeability of hydrogen in water is about 5-10 times that of dry film, and the permeability increases with increasing the relative humidity of the membrane.
