Title:
ELECTROLYTIC CELL FOR GENERATING GAS
Document Type and Number:
Japanese Patent JPS51130684
Kind Code:
A
Abstract:
An electrolyzer comprising a cathode and an anode, disposed in an aqueous electrolyte bath, the electrodes each having at least one active surface directed substantially in facing relation to at least one active surface of the electrode of opposite polarity. At least one of the electrodes is permeable to gas and is the source of a gas release at the time of operation of the electrolyzer. At least one portion of the active surface of the electrode permeable to the gas is covered by a porous layer constituted by at least one refractory oxide which is electrically insulative and chemically inert with regard to the electrolyte and to the products formed at the time of electrolysis. The layer has a homogeneous distribution of pore sizes of a value sufficient for the electrolyte to traverse this layer and impregnate the electrode, the mean value of the radii of the pores of the insulating refractory oxide layer being at least as small as one-tenth of that of the pores of the electrode that it covers. The electrode and the oxide layer form an element of self-supporting structure, the oxide layer constituting a surface portion in contact with the electrolyte.
