Use of the Proton Conductor Hydrogen Uranyl Phosphate Tetrahydrate as the Solid Electrolyte in Hydride-Air Batteries and Hydrogen-Oxygen Fuel Cells
Recent investigations1–9 of the good proton conductor HUO2PO4.4H2O (HUP) have opened up the prospects for its use as a solid electrolyte in a range of electrochemical cells involving transport of H+ ions. Hydrogen concentration cells of the type MHx∣HUP∣M′H2 y and electrochromic cells of the type HxWO3|HUP|HyWO9 3 have been previously described. Perhaps the most unique application of HUP is to hydride-air cells of the type MHx|HUP|O2,H2O, which we describe in this paper, and compare them to the more conventional hydrogen-type fuel cell of the kind H2|HUP|O2.
