Concentration fuel cell
Abstract
Abstract The present invention provides a fuel cell comprising a fuel chamber and oxidizer chamber, an electrolyte chamber having electrolyte therein, the electrolyte chamber being hermetically sealed from the first two chambers by a first closed electrode separating the electrolyte chamber from the oxidizer chamber, and by a second closed electrode separating the fuel chamber from the electrolyte chamber. Each of the electrodes are composed of a material selectively permeable to only one of the cell reactants and substantially impermeable to the others, their impurities, and reaction products. Said electrodes are formed by vapor deposition on a porous metal base of an easily removable metal coating which is selectively etched away.
