Title
(EN) REDUCED LEAKAGE METAL-AIR ELECTROCHEMICAL CELL
(FR) CELLULE ELCETROCHIMIQUE METAL-AIR A FUITES REDUITES
Abstract
(EN)
The invention relates to a metal-air electrochemical cell which exhibits good discharge performance under relatively high temperature, high humidity conditions. The cell has improved discharge performance at a temperature between about 25 °C and about 38 °C and a relative humidity external of the cell of between about 45 and about 95 percent. Leakage from the cell also can be reduced.
(FR)
L'invention concerne une cellule électrochimique métal-air dont les performances sont satisfaisantes en matière de décharge à température relativement élevée et sous humidité élevée. On observe des performances satisfaisantes à une température comprise entre environ 25 °C et environ 38 °C, avec une humidité externe relative comprise entre environ 45 % et environ 95 %. En outre, cette cellule est caractérisée par des fuites réduites.
