Abstract:
An ionic conduction device including a stack of layers, each layer including an electrolyte membrane having a pair of opposed surfaces, a gas permeable electrode in contact with each opposed surface, and there being a plurality of interconnects in electrical contact with the electrodes of the layers, to provide electrical continuity through the stack, wherein there is at least one gas flow path through the layers and the interconnects of the stack, and wherein at least one of the sides of the stack and/or in the or at least one of the gas flow paths through the stack, the layers provide a stepped configuration with the electrolyte membrane extending outwardly at the side and/or inwardly of the gas flow path respectively, beyond the electrodes in contact with the opposed surfaces of the electrolyte membrane, and the electrodes each extending outwardly of the side and/or inwardly of the gas flow path respectively, beyond the interconnects in electrical contact with the electrodes.
