AbstractAbstract
[en] Unlike conventional generation systems fuel cells use an electrochemical reaction between a fossil fuel and an oxidant to produce electricity through a flame less combustion process. As a result, fuel cells offer interesting technical and operating advantages in terms of conversion efficiencies and environmental benefits due to very low pollutant emissions. Among the different kinds of fuel cells the molten carbonate fuel cells are currently being developed for building compact power generation plants to serve mainly in congested urban areas in virtue of their higher efficiency capabilities at either partial and full loads, good response to power peak loads, fuel flexibility, modularity and, potentially, cost-effectiveness. Starting from an analysis of the most important degradative aspects of the corrosion of the separator plate, the main purpose of this communication is to present the state of the technology in the field of corrosion control of the separator plate in order to extend the useful lifetime of the construction materials to the project goal of 40,000 hours

AbstractAbstract
[en] Molten carbonate fuel cell (MCFC) systems are currently limited by several technical problems. The objectives of this project are to focus on these problems and develop materials and cell components that will ameliorate or eliminate them. Specifically, new ceramic materials are being investigated for dimensionally stable electrode materials with improved chemical and electrochemical properties over the present NiO cathode and Ni/Cr and Ni/Al anodes. Also, alternative electrolyte formulations to the present Li2CO3-K2CO3 are being studied to reduce nickel oxide solubility, minimize differential electrolyte migration, and reduce component corrosion

AbstractAbstract
[en] Molten carbonate fuel cell stacks are assembled from nickel coated stainless steel frames comprising the bipolar plate, the flanges for the wet seal and current transmitting structures and the cell components (anode, electrolyte matrix and cathode) which are introduced in the stack in the form of 'green foils' or pre-sintered metal sponges and which are transformed into the respective cell component by in-situ reactive sintering. 8 figs., 13 refs

AbstractAbstract
[en] Fuel cells technologies for stationary applications are expected to play a remarkable role in the field of next decade energy production systems ranging from some hundreds kW to some MW. The interest in using fuel cells to produce electric energy comes from the advantages that fuel cells offer in terms of high efficiency, good behavior at base and partial load, very low emissions, modularity (easy adjustment of plant capacity to power-demand increase), and reduced time to be spent for plant erection. At least four types of fuel cells can be considered suitable for stationary applications. With reference to their electrolyte they can be classified as: Polymeric Electrolyte Membrane Fuel Cells (PEMFC), Phosphoric Acid Fuel Cells (PAFC), Molten Carbonate Fuel Cells (MCFC) and Solid Oxide Fuel Cells (SOFC). Each of them works at a temperature level that is depending on the type of electrolyte. From a general point of view all the fuel cell technologies present, at various extents, the above listed advantages. Nevertheless specific features of each fuel cell type suggest to identify a specific field of application for each type of solution, in order to stress the potential advantages of any technology and minimize its possible drawbacks. Anyway the different level of maturity for the various fuel cell technologies does not allow an homogeneous comparison of technical and economical key parameters. PAFCs, due to their present commercial availability and operation experience, are well outlined in terms of performance and costs; on the contrary with regard to the other technologies--PEMFC, MCFC and SOFC--which are still under development, their commercialization is expected within a period of 7 to 13 years according to single technology maturity level (MCFC level seems to be more ready), kind of application, competitors, environmental constraints, etc

AbstractAbstract
[en] This paper presents a prediction method and corresponding Visual Basic program to evaluate the economic feasibility of the commercial fuel cells in utility systems. The economic feasibility of a fuel cell is defined as having a net present value (NPV) greater than zero. The basic process of the method is to combine fuel cell specifications and real energy market data to calculate yearly earning and cost for obtaining the NPV of fuel cells. The Fuel Cell Analysis Software was developed using Visual Basic based on the proposed method. The investigation of a 250 kW molten carbonate fuel cell (FuelCell Energy DFC300A) predicted that, for application specifically in Arizona, United States, no profit would result from the installation of this fuel cell. The analysis results indicated that the efficiency, investment cost, and operation cost are three key factors affecting potential feasibility of the commercial fuel cells
