The crystal, electrical and electrochemical properties of the new composite materials of (1-x)SrTi0.5Fe0.5O3-δ-xCe0.8(Sm0.8Sr0.2)0.2O2-δ (0≤x≤1, Δx= 0.25) prepared by solid phase method. Composites have no phase interaction. ...
Benzene electro-oxidation in a PEMFC for phenol and electricity cogeneration
(2005)
In the present investigation, the electrochemically-assisted oxidation of benzene in a H2-O2 proton exchange membrane fuel cell (PEMFC), for electricity and phenol cogeneration is studied. Experiments were carried out in ...
Bi4Cu0.2V1.8O11-delta based membrane electrochemical reactors for propane oxidation at moderate temperatures
(2005)
Bi4Cu0.2V1.8O11-delta membrane material was synthesized by following the solid-state method. The oxygen permeation flux at 673 K was found to be 0.5 ml/cm(2) by the use of an external electric power source. The oxidation ...
Recent advances in direct alcohol PEMFCS
