Carbonate fuel cells: Milliwatts to megawatts   总被引:3,自引:0,他引:3  
The carbonate fuel cell power plant is an emerging high efficiency, ultra-clean power generator utilizing a variety of gaseous, liquid, and solid carbonaceous fuels for commercial and industrial applications. The primary mover of this generator is a carbonate fuel cell. The fuel cell uses alkali metal carbonate mixtures as electrolyte and operates at 650 °C. Corrosion of the cell hardware and stability of the ceramic components have been important design considerations in the early stages of development. The material and electrolyte choices are founded on extensive fundamental research carried out around the world in the 60s and early 70s. The cell components were developed in the late 1970s and early 1980s. The present day carbonate fuel cell construction employs commonly available stainless steels. The electrodes are based on nickel and well-established manufacturing processes. Manufacturing process development, scale-up, stack tests, and pilot system tests dominated throughout the 1990s. Commercial product development efforts began in late 1990s leading to prototype field tests beginning in the current decade leading to commercial customer applications. Cost reduction has been an integral part of the product effort. Cost-competitive product designs have evolved as a result. Approximately half a dozen teams around the world are pursuing carbonate fuel cell product development. The power plant development efforts to date have mainly focused on several hundred kW (submegawatt) to megawatt-class plants. Almost 40 submegawatt units have been operating at customer sites in the US, Europe, and Asia. Several of these units are operating on renewable bio-fuels. A 1 MW unit is operating on the digester gas from a municipal wastewater treatment plant in Seattle, Washington (US). Presently, there are a total of approximately 10 MW capacity carbonate fuel cell power plants installed around the world. Carbonate fuel cell products are also being developed to operate on coal-derived gases, diesel, and other logistic fuels. Innovative carbonate fuel cell/turbine hybrid power plant designs promising record energy conversion efficiencies approaching 75% have also emerged. This paper will review the historical development of this unique technology from milliwatt-scale laboratory cells to present megawatt-scale commercial power plants.  相似文献

Transportation sector is the important sector and consumed the most fossil fuel in the world. Since COVID-19 started in 2019, this sector had become the world connector because every country relies on logistics. The transportation sector does not only deal with the human transportation but also relates to logistics. Research in every country has searched for alternative transportation to replace internal combustion engines using fossil fuel, one of the most prominent choices is fuel cells. Fuel cells can use hydrogen as fuel. Hydrogen can be fed to the fuel cells to provide electric power to drive vehicles, no greenhouse gas emission and no direct combustion required. The fuel cells have been developed widely as the 21st century energy-conservation devices for mobile, stationary, and especially vehicles. The fuel cell electric vehicles using hydrogen as fuel were also called hydrogen fuel cell vehicles or hydrogen electric vehicles. The fuel cells were misconceived by several people that they were batteries, but the fuel cells could provide electric power continuously if their fuel was provided continuously. The batteries could provide electric power as their only capacities, when all ions are released, no power could be provided. Because the fuel cell vehicles play important roles for our future transportation, the overall review for these vehicles is significantly interesting. This overall review can provide general and technical information, variety of readers; vehicle users, manufacturers, and scientists, can perceive and understand the fuel cell vehicles within this review. The readers can realize how important the fuel cell technologies are and support research around the world to drive the fuel cell vehicles to be the leading vehicles in our sustainable developing world.  相似文献

The energy distribution of the world is in a critical transition from traditional fossil fuel to new clean energy. Actually, the fuel cell is favored by researchers as an efficient and clean energy conversion equipment. The anion exchange membranes (AEMs) with excellent performance and long service life will become the development trend of alkaline fuel cells in the future. Compared with proton exchange membrane fuel cells (PEMFCs), its advantages of affordable price, work safety, and non-precious metal participation are widely favored by researchers. This paper reviews the performance of characteristics, synthesis methods, modification methods, and alkaline stability protection of anion-exchange polyelectrolytes (AEPs), and the current research and development status of AEPs used in AEMs are summarized. The evaluation and comparison of different types of AEPs and AEMs based on different AEPs are put forward. This review is expected to further deepen the understanding of AEPs in AEMFC.  相似文献

Fuel cells are expected to soon become a source of low- to zero-emission power generation for applications in portable technologies and electric vehicles. Allowing development of high quality solid electrolytes and production of smaller fuel cells, significant progress has been made in the development of fuel cell membranes using nanotechnology. Nanostructures have been recognized as critical elements to improve the performance of fuel cell membranes. This paper provides an overview of research and development of nanostructured membranes for different fuel cell applications and focuses on improvement of fuel cell membranes by these nanostructures. Theoretical studies using molecular-scale modeling and simulation of fuel cell membranes have also been included in this review. Other issues regarding the technology limitations, research challenges and future trends are also reviewed.  相似文献

Fuel cells, as energy conversion devices, are receiving attention from researchers and developers due to their high efficiency and environmentally friendly characteristics. However, despite the prospect of booming fuel cell development, the overall quality and level of development still need to be improved, and safety is one of the key development indicators. This article presents a scientometric and knowledge network analysis of fuel cell safety based on information from 890 relevant publications in the Web of Science Core Collection. The bibliometric software VOSviewer and Co-Occurrence are used for in-depth analysis and visual presentation of the publication information. The results show that the first publication is released in 1991, and this research field has exploded since 2017. Moreover, the USA and China have the strongest cooperation in this field. The hot areas of fuel cell safety research are focused on five clusters: electrode and catalyst safety, fuel cell electric vehicle safety, hydrogen safety, energy generation and storage safety, and solid oxide fuel cell safety. This article maps the knowledge of research related to fuel cell safety and helps readers gain a quick perspective on the research structure and future directions in this field.  相似文献

Most of car manufacturers around the world have launched important research programs on the integration of fuel cell (FC) power generators into cars. Despite the first achievements, fuel cell systems are still badly known, particularly when talking about fault diagnosis and predictive maintenance. This paper proposes a first step in this way by introducing a simple but also efficient diagnosis-oriented model of a proton exchange membrane fuel cell (PEMFC). The considered diagnosis model is here a fuzzy one and is tuned thanks to genetic algorithms.  相似文献

Fuel cell vehicles, as a substitute for internal-combustion-engine vehicles, have become a research hotspot for most automobile manufacturers all over the world. Fuel cell systems have disadvantages, such as high cost, slow response and no regenerative energy recovery during braking; hybridization can be a solution to these drawbacks. This paper presents a fuel cell hybrid bus which is equipped with a fuel cell system and two energy storage devices, i.e., a battery and an ultracapacitor. An energy management strategy based on fuzzy logic, which is employed to control the power flow of the vehicular power train, is described. This strategy is capable of determining the desired output power of the fuel cell system, battery and ultracapacitor according to the propulsion power and recuperated braking power. Some tests to verify the strategy were developed, and the results of the tests show the effectiveness of the proposed energy management strategy and the good performance of the fuel cell hybrid bus.  相似文献
