摘要：

A halogen such as chlorine is generated by the electrolysis of aqueous halides in an electrolysis cell which includes an anode and a cathode separated by an ion transporting membrane. At least the cathode, which is a mass of noble metal catalytic particles and particles of a suitable binder, is bonded to the surface of the membrane. An oxygen containing gaseous stream is brought into contact with the bonded cathode to depolarize the cathode and prevent or limit discharge of hydrogen at the cathode, thereby substantially reducing the cell voltage.
