Abstract
A means for producing electricity from an electrochemical reaction as well as for storing and recovering electrical energy, which utilize electrochemical reactions. The basic galvanic cell comprises a first solid non-porous body capable of storing large quantities of an ionizable species (this is the case with a metal hydride and hydrogen) the ionized species (H.sup.+ ions) migrating through a thin-film solid electrolyte (alumina) towards a second body (oxygen or atmospheric air) where the electrochemical reaction takes place (and the water produced is easily eliminated). The internal resistance of the cell is low because the electrolyte is in thin-film form. The technology of thin-film deposition is possible because the first body is a non-porous solid.
