ABSTRACT:
The present invention relates to a metal-air cell having a piezo-electric pump. The piezo-electric pump has a characteristic of moderate change of air flow speed relative to the pressure. Accordingly, the air supply speed can be controlled easily. This characteristic enables small and simple construction of the metal-air cell with the maximum electrical energy being obtained from the cell.
