The present invention provides a fuel cell in which electricity is generated and a paraffin is converted to an olefin. Between the anode and cathode compartment of the fuel cell is a ceramic membrane of the formula BaCeALYOwherein A is selected from the group consisting of Hf and Zr and mixtures thereof, e is from 0.1 to 0.5, L is a lanthanide and f is from 0 to 0.25 and &#x3b4; is the oxygen deficiency in the ceramic.

Paraffin fuel cell

The present invention provides a fuel cell in which electricity is generated and a paraffin is converted to an olefin. Between the anode and cathode compartment of the fuel cell is a ceramic membrane of the formula BaCeLYOwherein L is a lanthanide and f is from 0 to 0.25 and &#x3b4; is the oxygen deficiency in the ceramic.

An electrochemical process for the oxidation of an alkane to at least one corresponding alkene uses an electrochemical cell having an anode chamber on one side of a proton conducting medium, and a cathode chamber on the other side of the said medium. The alkane is oxidized in the anode chamber to produce at least one corresponding alkene and protons are transferred through a proton conducting membrane to the cathode chamber where protons combine with a proton acceptor, while generating electricity and water. An apparatus for use in the process is also provided.

Electrochemical process for oxidation of alkanes to alkenes

The present invention relates to an anode catalyst for use in the electrochemical oxidation of HS to elemental sulfur and water, specifically in a fuel cell having an ion-conducting membrane. The catalyst comprises a material prepared from two or more metal sulfides of the formula MS, wherein M is selected from the group consisting of Co, Ni, Fe, Mo, Cu, Cr, W and Mn, and x is between about 1.0 and about 2.5; a conductive material suitable for fuel cell operation; and a porous material. The invention further provides methods of preparing the catalyst, fuel cells comprising the catalyst and methods of electrochemically oxidizing HS using the catalyst.
