Patent ID: 7205065

Claim:
A gastight cell for the storage of electrochemical energy, comprising at least one positive nickel oxide electrode and at least two hydrogen-storing negative electrodes, a hydrophilic separator being arranged between the positive and negative electrodes, with n positive electrodes and (n+1) negative electrodes, the two outmost electrodes being negative electrodes, which are each flanked by a respective gas-permeable, hydrophobic transport element, and an alkaline electrolyte or an alkaline electrolyte mixture, wherein one or more additional negative electrodes are provided with a respective gas-permeable, hydrophobic transport element, said transport elements being positioned to accommodate a flow of gas through said transport elements, and wherein all of the negative electrodes are hydrogen-storing negative electrodes, and wherein every second negative electrode is split into two parts, the two parts being separated from one another by a hydrophobic, gas-permeable transport element.
