Abstract: A catalyst for the generation of hydrogen from a small organic molecule comprises a tertiary metal composition where: the first metal is either Pt or Ru; the second metal is at least one of Pt, Ru, Au, Pd, Rh, Ir, Os, and/or Re; and Bi, primarily present in the form of an oxide or of a mixture of oxides and carbonates and in the +3 oxidation state. A portion of the first and/or second metal may be in the form of an oxide. The catalyst can be in the form of a nanoparticle and supported on an inert substrate, such as carbon. The catalyst can be used for dehydrogenation of formic acid or other small organic molecules in a liquid state at ambient pressures and at temperatures below the boiling point of the liquid. The liquid can be an aqueous solution of the small organic molecule.

Abstract: An electrochemical device such as a battery and a fuel cell having two electrolytes between the anode and the cathode. The electrochemical device is preferably arranged with an alkaline electrolyte in contact with the anode and an acidic electrolyte in contact with the cathode. The electrolytes are separated by a bipolar membrane that preferably also provides ionic conductivity between the two electrolytes and also generates a supply of protons and hydroxide anions. The electrochemical device achieves fifty percent higher operating voltage and power compared to fuel cells with a single electrolyte.
