Abstract
The present invention provides improved devices for the production of electrical energy from mixtures of oxygen (i.e., pure oxygen, air, or a similar source of free oxygen) and fuel (i.e., hydrogen and/or a hydrogen-yielding fuel). The devices generally comprise: a first electrode means for receiving electrons; a second electrode means for supplying electrons; and an electrolytic diffusion means, positioned between the two electrode means, for conducting ions from one electrode means to the other electrode means and for conducting oxygen and fuel, oxygen and hydrogen, or oxygen and a combination of fuel and hydrogen from one electrode means to the other electrode means (FIG. 1). At least one of the electrode means is permeable. Additionally, the first electrode means comprises a catalytic material which is a highly active catalyst for the formation of H.sub.2 O.sub.2 from H.sub.2 and O.sub.2.
