Increasing efficiency and decreasing cost are the main purposes in the design of the power generation systems. In this study two hybrid systems: solid oxide fuel cell (SOFC)-gas turbine (GT) and SOFC-GT-steam turbine (ST); are considered. Increasing the SOFC input temperature causes thermodynamics improvement in the hybrid system operation. For this purpose, using two set of SOFC reactants heat...

In the present study, thermo-economic analysis of a combined solid oxide fuel cell (SOFC) with a gas turbine, a generator-absorber heat exchanger (GAX) and heating process heat exchanger for heating, cooling and power production as a tri-generation system is conducted. Also, an external steam reformer is applied to convert methanol as oxygenated fuel to hydrogen for the electrochemical process ...

Solid oxide fuel cell (SOFC) is an energy conversion device that can directly convert the chemical of carbonaceous fuels into electricity. Solving problem carbon deposition in conventional nickel-based anode essential to improving performance SOFC when operating on fuels. Although impressive progress has been made development alternative materials, anodes with superior catalytic activity for ar...

In this study, we used quantum mechanics (QM) to investigate steam reforming of methane on Ni-alloy catalyst surfaces and to examine the effect of anode material modifications on the catalytic processes in a solid oxide fuel cell (SOFC). The conventional Ni anode suffers from coking, coarsening, and sulfur poisoning because of the decomposition of hydrocarbon fuels, Ni particle agglomeration at...

A highly efficient catalyst, MoV(0.3)Te(0.17)Nb(0.12)O, used for acrylic acid (AA) production from propane, was used as an anodic catalyst in an SOFC reactor, from which AA and electric power were cogenerated at 400-450 degrees C.

Solid Oxide Fuel Cells (SOFC) integrated in Gas Turbine (GT) cycles (often denoted as hybrid systems) is a promising concept for production of efficient and low-polluting electrical power. The SOFC can produce electric power at an electrical efficiency of about 55%, and when it is combined with a GT, studies show that the net electrical efficiency can be increased up to 70% Pålsson et al. (2000...

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 ...
