The invention discloses an innovative fuel cell-type electrochemical energy conversion device and method of potentially high power density capability, suitable especially for stand-alone applications such as electricity-powered vehicles The inventive device, named “storage fuel cell”, may be viewed as a converted storage battery, including plates, electrolyte and separators that can be similar to the ordinary known lead-acid battery. Thus it can be charged from an electrical source, or discharged across an external load with the usually high surge current features of storage batteries. An innovative additional charging mode of the storage fuel cell, by chemical reactions of each electrode with fuel and oxidizer supplied at specific flow ratios, is however the prime object of this invention. Whereas all types of prior art fuel cells exchange ions between the electrodes, across the electrolyte, each of the electrodes of the instant fuel cell independently exchanges ions, only using their adjoining electrolyte.
