Abstract
Disclosed herein is a gas permeable electrode which comprises a gas permeable layer and a reaction layer, the reaction layer comprising hydrophobic portions and hydrophilic portions. Electrolyte penetrates into the reaction layer and does not penetrate into the gas permeable layer, and only the gas produced on the electrode and the gas supplied penetrate into the gas permeable layer. The gas can be released from the rear side of the electrode and the reaction surface thereof is never covered with the gas.

A gas permeable electrode which comprises a gas permeable layer comprising hydrophobic resins and hydrophobic carbon blacks and a reaction layer comprising a semi-hydrophobic porous body prepared by the coagulation of hydrophobic resins, hydrophobic carbon blacks and hydrophilic carbon blacks, both layers being attached to each other producing a finished electrode, the electrolyte impregnating the hydrophilic carbon blacks of the reaction layer to be held therein, and the hydrophobic carbon blacks thereof constituting gas passages, the finished electrode being substantially free from surfactant.
A gas permeable electrode which comprises a gas permeable layer comprising hydrophobic resins and hydrophobic carbon blacks and a reaction layer comprising a semi-hydrophobic porous body prepared by the coagulation of hydrophobic resins, hydrophobic carbon blacks and hydrophilic carbon blacks supporting catalysts therein, both layers being attached to each other producing a finished electrode, the electrolyte impregnating the hydrophilic carbon blacks of the reaction layer to be held therein, and the hydrophobic carbon blacks thereof constituting gas passages, the finished electrode being substantially free from surfactant.
A gas permeable electrode which comprises a gas permeable layer comprising hydrophobic resins and hydrophobic carbon blacks and reaction layer comprising an ion exchange resin film and a semi-hydrophobic porous body prepared by the coagulation of hydrophobic resins, hydrophobic carbon blacks and hydrophilic carbon blacks, both layers being attached to each other producing a finished electrode, the electrolyte impregnating the hydrophilic carbon blacks of the reaction layer to be held therein, and the hydrophobic carbon blacks thereof constituting gas passages.
