The results of theoretical studies the possibilities using hybrid solid oxide fuel cell–gas turbine (SOFC-GT) systems for marine power plants are presented. A 500 kW auxiliary plant scheme stacks SOFCs in combination with a regenerative gas operating over-expansion based on our recent patent application is proposed. mathematical modelling showed opportunity to obtain efficiency about 55% optima...

Mg-based materials have been investigated as hydrogen storage materials, especially for possible onboard storage in fuel cell vehicles for decades. Recently, with the development of large-scale fuel cell technologies, the development of Mg-based materials as stationary storage to supply hydrogen to fuel-cell components and provide electricity and heat is becoming increasingly promising. In this...

developed lOkW class tubular SOFC modules for stationary power generation using Japanese town gas (13A) as fuel. A small module which consisted of 5 stacks (a stack consisted of 2 x 6 cells) generated 1.5kW at 0.2Alcm2 and achieved 55%-LHV efficiency at an average temperature of 900°C. A thermally self-sustaining module consisting of 20 stacks achieved 6.5kW at 0.2A/cm2 and 50%-LHV. relatively ...

The Zero Emission Coal Alliance (ZECA) is developing an integrated zero emission process that will generate clean energy carriers (electricity or hydrogen) from coal. The process exothermically gasifies coal using hydrogen to produce a methane rich intermediate state. The methane is subsequently reformed using water and a CaO based sorbent. The sorbent supplies the energy needed to drive the re...

a set of multicomponent perovskite oxide nanoparticles based on la1-xsrxco1-yfeyo3-δ(lscf) were prepared by a simple chemical precipitation method for application in low temperature solid oxide fuel cells (lt-sofc) as cathode materials.  the precursor materials used in this synthesis were lanthanum nitrate hexahydrate [la(no3)3.6h2o], strontium nitrate [sr(no3)2], cobalt nitrate hexahydrate [co...

Nanocrystallite ceria-doped scandia-stabilized zirconia (1Ce10ScSZ) powders are prepared using a combination of co-precipitation and hydrothermal treatments. Power density of 1.0 W cm(-2) is obtained at 1.6 A cm(-2) and 800 °C due to the drastic reduction of ohmic and polarization resistance in the SOFC cell.

SERS provided by sputtered silver was employed to detect trace amounts of chemical species on SOFC electrodes. Considerable enhancement of Raman signal and lowered detection threshold were shown for coked nickel surfaces, CeO(2) coatings, and cathode materials (LSM and LSCF), suggesting a viable approach to probing electrode degradation and surface catalytic mechanism.
