... which affect the lifetime of the traditional rectangular shape MCFCs. The main aim of this research is to evaluate the possibility of not installing the porous ceramic matrix in order to reduce the gas crossover problems of MCFCs and improve the cell lifetime. Thus, the new single cell was mainly...

...Dongho Seo; Sangsun Park; Byeong-Mu Lim; Yong-Soo Cho; Yong-Gun Shul The multicomponent proton conducting ceramics SiO 2 – TiO 2 – ZrO 2 – P 2 O 5 (STZP) and SiO 2 – TiO 2 – ZrO 2 – P 2 O 5 – Bi 2 O 3 with three different compositions (STZPBi3, STZPBi10, and STZPBi15) were synthesized via a wet...

...-impregnation route ensures a very homogeneous particle dispersion and a good adhesion of Ag to the ceramic matrices. The cells were successfully operated to produce the maximum power densities of 0.41 W cm − 2 ( 1.27 A cm − 2 , 0.32 V), 0.83 W cm − 2 ( 2.23 A cm − 2 , 0.37 V), and 1.05 W cm − 2 ( 2.39 A cm − 2...

...B. A. Haberman; A. J. Marquis A typical segmented-in-series tubular solid oxide fuel cell (SOFC) consists of flattened ceramic support tubes with rows of electrochemical cells fabricated on their outer surfaces connected in series. It is desirable to design this type of SOFC to operate...

...Sergey Yarmolenko; Jag Sankar; Nicholas Bernier; Michael Klimov; Jay Kapat; Nina Orlovskaya The phase composition and sintering behavior of two commercially available 10 mol % Sc 2 O 3 – 1 mol % Ce O 2 – Zr O 2 ceramics produced by Daiichi Kigenso Kagaku Kogyo (DKKK) and Praxair have been studied...

... of the electrode reactions are compared. The comparison shows that the spatially discretized reaction model is indeed necessary for the reliable assessment of temperature gradients in the ceramic SOFC components. The heat generated by this irreversible voltage loss is released at the cathodic and anodic reaction...

...B. A. Haberman; J. B. Young The Rolls-Royce integrated-planar solid oxide fuel cell (IP-SOFC) consists of ceramic modules with electrochemical cells printed on the outer surfaces. The cathodes are supplied with oxygen from air flowing over the outside of the module and the anodes are supplied...

...Hitoshi Takamura; Yusuke Aizumi; Atsunori Kamegawa; Masuo Okada Oxygen permeable ceramics based on mixed conductors are attracting much attention for use in partial oxidation of hydrocarbons as a novel technique for syngas and pure hydrogen production. This paper describes the preparation...

...M. Dhallu; J. A. Kilner To date, a number of ceramic oxides with the perovskite structure have been proposed as membrane materials for the selective separation of oxygen and the partial oxidation of hydrocarbons due to their high oxygen permeation fluxes. In contrast, their instability under...
