Abstract: A short overview of recent work on electroceramic materials relevant to methane-fueled SOFC systems is given. Various fuel feed options are considered, such as pure methane, biogas, and the addition of reforming agents. The principle and implemen ...
For the development of a rechargeable zinc/air battery, La0.6Ca0.4CoO3 (perovskite) catalyzed bifunctional oxygen electrodes and 3-D zinc electrodes were prepd. and tested in a bipolar zinc/air battery. In addn., a numerical model for the zinc electrode wa ...
For the development of a rechargeable zinc/air battery, La0.6Ca0.4CoO3-catalyzed (perovskite) bifunctional oxygen electrodes and pasted zinc electrodes were prepd. and tested in monopolar zinc/air cells. In addn., a bipolar Zn/air stack was tested using re ...
In this process a carrier (Mn+) is electrochem. oxidized (or reduced) and then allowed to react with the org. compd. in a sep. vessel. When the reaction is complete a sepn. of product is made and the spent liquor is returned to the electrochem. cell where ...
The loss of current efficiency in the indirect 2-stage electrochem. process using the Mn2+/Mn3+ system is due to the oxidn. of orgs. present in the recycled electrolyte. There is no evidence of electrode poisoning under the exptl. conditions studied (88% H ...
The perovskite-type mixed oxide La0.3Sr0.55Ti0.95Ni0.05O3−δ (LSTN) is demonstrated to exhibit the remarkable property of structural regeneration, where Ni can be reversibly exsoluted from the host perovskite lattice resulting in a regenerable Ni catalyst f ...
