Application of power electronics with the US DOE distributed generation programme
Power electronics play an important role in achieving affordable, highly fuel-efficient fuel cell power generation plants and will enable the US Department of Energy's Office of Fossil Energy Fuel Cells programme to achieve higher national goals: environmental, economic and energy security. The initial focus on power electronics has been to understand the interactions between the SOFC stack, the ...

Effect of reforming on the overall efficiency of a solid oxide fuel-cell based power plant system fed by methane
In the present work, energy and exergy system analysis are used to estimate the thermodynamic performance of a SOFC system fuelled by methane. More precisely, the present work examines in detail the influence of the presence or absence of the reformer within the whole apparatus and the consequent energy and exergy losses due to the reforming process. It was found that the exergetic efficiency for ...

Exergy analysis of a combined fuel cell and Gas Turbine Power Plant with intercooling and reheating
This paper presents a comparative exergy study of the performance of various gas turbine power generation plants and a high temperature Solid Oxide Fuel Cell (SOFC). The overall system is analysed and its exergy efficiency and exergy destruction are obtained, as well as individual models of each component. The results for selected operating conditions are compared against past literature data. ...

Who uses innovative energy technologies, when and why? The case of fuel cell MicroCHP in households
Users can play an important role in the diffusion of sustainable energy technologies. Using a postal survey and focus group discussions, the paper explores the characteristics, motives and expectations of household users in the case of fuel cell?driven small combined heat and power plants. (Potential) users are highly educated and well off, almost exclusively male and relatively old. Their main ...

Combined cycles for CO2-capture with high efficiency
The presented paper gives an overview on combined cycles for CO2-capture with high efficiency focussed on processes using a Solid Oxide Fuel Cell (SOFC), because of the air separating ability of the SOFC-membrane. The SOFC-membrane is only permeable for oxygen ions, so the cathode exhaust gas is oxygen depleted air, which should be discharged to the atmosphere after recycling or using the heat ...

Exergy analysis of gas turbine – solid oxide fuel cell–based combined cycle power plant
Fuel cell technology is one of the promising systems for cleaner and competitive alternate power generation systems. When the high temperature fuel cells like solid oxide fuel cell and molten carbon fuel cell are integrated with the gas turbines, the total thermal efficiency of the combined cycle can be obtained greater than 60%. In the present work, thermodynamic analysis of SOFC–GT combined ...

Development of a lignite-fired power plant concept with integrated pressurised fluidised-bed drying and fuel cells
In the coming decades, lignite will become one of the most important fuels for power production in Germany. In the last five years, Vattenfall Europe and RWE have put power plants of the 800–1000 MW class with efficiency of up to more than 43% into service. Four to five per cent efficiency can further be gained by using pre-dried lignite as fuel (BOA plus concept of RWE). Additional steps are ...

Key Objectives in Modern Fuel Cell Studies
What are Fuel Cells? Fuel cells use the chemical energy of hydrogen or an alternative fuel to cleanly and efficiently produce electricity. Using hydrogen as the fuel only produces water, heat, and electricity. Hydrogen (the fuel) is supplied continuously, unlike in a battery, and a dynamic equilibrium is maintained. ...

Greenhouse gas emissions of fossil fuel-fired power plants: current status and reduction potentials, case study of Iran and Canada
In this paper, methodology to estimate GHG emissions from electricity generation sector using Iran as an example was first explained. Then different scenarios to reduce GHG emissions were evaluated for two countries: Canada and Iran. The results demonstrated that there were great potentials for GHG emission reduction in both countries. These potentials were evaluated by introducing eight ...

Commercial Demonstration of a PEM Fuel Cell for Power Generation
The chlor-alkali industry, one of the largest chemical industries in India and growing at an annual rate of 3.3%, is expected to grow along with the growing Indian economy. This MW size proton-exchange membrane (PEM) fuel cell product captures hydrogen produced in the chlor-alkali industry to create on site electricity and provide plant operators up to 20% of electricity savings. The electricity ...
