ABSTRACT:
An electrochemical battery cell with an oxygen reduction electrode and having improved electrolyte leakage resistance. The cell includes a component, disposed between the oxygen reduction electrode and an air inlet in the cell housing, through or around which air can pass. Upon contact with electrolyte, the component is transformed to form an electrolyte seal.
