摘要
A composite hydrogen purification membrane comprises an anode for hydrogen oxidation, a cathode for hydrogen reduction, with a proton conductor disposed between and in contact with the anode and the cathode. Electrons are conducted between the anode and cathode through an external connection, with the electron flow generated by the difference in hydrogen partial pressure between the anode and cathode sides of the membrane. Thus the composite hydrogen purification membrane provides high hydrogen permeability and selectivity relative to the impurities in a feed gas, producing pure hydrogen without requiring an external voltage source.
