  • Synthetic jet for admitting and expelling reactant air
    Patent number: 6759159
    Abstract: The present invention relates to a synthetic air jet for a metal-air battery. A synthetic air jet can be housed within, incorporated into, or attached to a battery casing to generate a convective air flow for an air cathode of a metal-air cell contained within the casing. A means for activating the synthetic air jet controls the air flow through the battery casing. When the synthetic air jet is activated, the internal volume of the synthetic air jet changes. The expansion and contraction of the synthetic air jet creates an air flow through the battery, thus providing reactant air for the air cathode of the metal-air cell.
