新型燃料电池的研究Research on new type fuel cells

摘要

能源是经济的的基础。人类为了更有效的的利用能源，一直进行着不懈的努力。利用能源的方式历史上有过多次革命性的变革，每一次变革都极大的推进了社会文明的发展。二次能源中，蒸汽由于传输距离短，难以存储而应用受限；电能虽然传输快、传输距离远，但存在传输过程中存在能量损耗大，难于存储的缺点；而氢能既能远距离传输、又能方便存储，因而成为二十一世纪的理想能源，二十一世纪也被称为氢世纪。多年来人们一直努力寻找既有较高能源效率又不污染环境的能源方式，因而引导出燃料电池发电技术。燃料电池是不经燃烧过程直接把燃料的化学能转化为电能的装置，具有能量转换效率高、污染物排放量少的独特优点。燃料电池凭借着它独特的优势应用在各个领域，加速了社社会的发展，推进了社会的文明。本文简述了燃料电池技术，各类燃料电池的原理以及它们各自的特点，并介绍目前燃料电池在国内外的应用现状，同时指出目前影响燃料电池商品化的主要因素。

Abstract

Energy is the basis of the economy. Human beings in order to make more effective use of energy, has been making unremitting efforts. The history of the use of energy, there have been several revolutionary changes each time changes are greatly promoted the development of our society. Secondary energy in the steam due to short transmission distance, it is difficult to store and the application is limited; electricity transmission faster, the transmission distance, but there is energy loss in the transmission process, difficult to store shortcomings; hydrogen both long-distance transmission. can facilitate the storage, and thus become the ideal energy of the twenty-first century, the twenty-first century is also known as a hydrogen century. Over the years people have been trying to find the energy efficiency of higher energy without polluting the environment, and thus lead to a fuel cell power generation technology. The fuel cell is not directly by the combustion process the fuel chemical energy converted into electrical energy, with the unique advantages of high energy conversion efficiency of the discharge of pollutants.

The fuel cell by virtue of its unique advantages of application in various fields to accelerate the social development of society, and promote the social civilization. In this paper, the fuel cell technology, the principle of various types of fuel cells and their respective characteristics, and describes the application of fuel cells at home and abroad, noting that the main factors affecting the commercialization of fuel cell.

Keywords: new energy; fuel cell; high efficiency; environmental protection.
