This paper presents the performance analysis of a planar solid-oxide fuel cell (SOFC) under direct internal reforming conditions. A detailed olid-oxide fuel cell model is used to study the influences of various operating parameters on cell performance. Significant differences in efficiency nd power density are observed for isothermal and adiabatic operational regimes. The influence of air numbe...

The irradiation of a thorium target by light charged particles (protons and deuterons) leads to the production of several isotopes of medical interest. Direct nuclear reaction allows the production of Protactinium-230 which decays to Uranium-230 the mother nucleus of Thorium-226, a promising isotope for alpha radionuclide therapy. The fission of Thorium-232 produces fragments of interest like M...

in this paper the role of super paramagnetic iron oxide nanoparticles (spi) on platinum nanoclusters on activated carbon (pt/c) for electrocatalytic oxygen reduction reaction was considered. four composites of pt/c and super paramagnetic iron oxide nanoparticles were prepared with the same total composites weight and different loading of pt/c (1.2, 0.6, 0.4 and 0.3 mg ). the composite attached ...

in this work, the strontium-doped lanthanum manganite- a ceramic material- used as cathode in solid oxide fuel cells. an impression of grinding time on the structural and thermal properties of sr-doped lamno3 system with la1-xsrxmno3 (x=0.2) stoichiometric ratio was investigated. the nano crystallite lsm powder with cubic structure was prepared by varying the milling time of planetary monomill ...

an efficient procedure is presented for the evaluation of solid oxide fuel cell (sofc) anode microstructure triple phase boundary length (tpbl). triple phase boundary- the one that is common between three phases of the microstructure- has a great influence on the overall efficiency of sofc because all electrochemical reactions of anode take place in its vicinity. therefore, evaluation of tpbl f...

The ability of Pelobacter carbinolicus to oxidize electron donors with electron transfer to the anodes of microbial fuel cells was evaluated because microorganisms closely related to Pelobacter species are generally abundant on the anodes of microbial fuel cells harvesting electricity from aquatic sediments. P. carbinolicus could not produce current in a microbial fuel cell with electron donors...
