Abstract
A bipolar battery intercell separator having three layers is disclosed. The two outer layers consist of a porous, hydrophobic, electrically conductive composite of carbon and a fluorocarbon binder hydrophobizing agent. The inner layer consists of a porous, hydrophobic, electrically conductive composite of carbon and a fluorocarbon binder hydrophobizing agent and a precious metal catalyst suitable for recombining hydrogen and oxygen at temperatures in the range of about -30.degree. to +150.degree. C. The precious metal catalyst is isolated from the electrolyte to prevent poisoning of the battery electrodes.
