In recent years,major research has been focused on alternative and renewable energy sources to replace our current reliance on fossil fuel.Some microorganisms can convert chemical energy from a wide r
A 5-kW dynamic solid oxide fuel cell(SOFC)system with a second air bypass has been developed with a model to perform both steady-state and dynamic analysis in this paper.Then identifies and addresses
Bipolar plates of Hydrogen-Oxygen Fuel Cell is the core of the parts,and the bipolar plates that constitutes about 70%of the stack weight and 60%of the stack cost become the main obstacle of the comme
世界性的能源议题,其中再生能源是备重视的,特别是燃料电池发展至今,在专利、技术的突破,让燃料电池系统整合有充份的运行,也使得在台湾明道大学发展出第一部的燃料电池车。如今整体的燃料电池系统中,各项组件的发展、及技术突破,就相当的重要,本研就针对燃料电池双极板为主要研究对像。
煤炭是地球上储量最丰富、分布最广泛和最廉价的化石能源.2013年,煤炭占到全球一次能源消费的30%.未来几十年,煤炭在世界能源格局中的重要地位仍不可替代.煤炭的最大消费者是燃煤电厂,其发电量占全球发电总量的40%以上.同时,燃煤发电也是最主要的环境污染源之一.清洁高效的煤电技术无疑是可持续发展亟需的一项重大技术.固体氧化物燃料电池(solid oxide fuel cells,SOFCs)以其燃料
With the rapid development of the society,environment and energy problems are urgent to be resolved all around the world.Microbial fuel cell (MFC) is a new method for treating organic wastewater and s
Recently,dissimilar materials welding hasbeen increasingly considered in industry because of its severalbenefits including reduction of material costs and improvements indesign flexibility.However,lit
Austenitic stainless steels are expected to be used for high-pressure hydrogen storage in fuel cell vehicles,however,they are sensitive to hydrogen embrittlement (HE);thus the application of the mater
作为一种无碳能源,氢被认为是21世纪的重要能源载体。氢的最小点火能量在易燃气体中是最小的,任何形式的氢泄漏均极易被静电等点火源点燃。所以掌握氢气喷射火焰的特性是极为重要的。本文建立了高压氢气喷射火焰特性数值模型,首先研究了不同喷嘴结构对喷射火焰形状及危险区域的影响,结果表明裂缝式扁平喷嘴的火焰大小主要取决于喷嘴的长宽比。然后对喷嘴直径和泄放压力对氢气喷射火焰形状和危险区域的影响进行了研究,发现圆形
掺氢天然气技术是推进风能、太阳能高效利用的有效途径。本文介绍了利用现有天然气管道进行掺氢天然气输送的主要安全问题。总结了掺氢天然气与材料相容性、泄漏与集聚、完整性管理及风险评估等方面的研究现状。讨论进一步掺氢天然气管道输送研究所需解决的安全问题,可为我国开展掺氢天然气管道输送的安全研究提供参考。
