制氢技术研究进展及在燃料电池中的应用前景

分析了当前能源现状和形势,并对氢的特点、制氢技术的新近研究进展进行了阐述。氢能作为一种很有应用前景的载能体,已得到越来越广泛的研究和应用。在化学制氢、电解水制氢、生物制氢这3种制氢模式中,化学制氢仍是近期主要的制氢方式,其中催化重整制氢仍然是大规模制氢的主流,随着燃料电池这一环境友好的发电方式在技术上的不断突破,许多其他的制氢技术也得到了迅速的发展,并将伴随着燃料电池、氢燃料发动机等技术的发展和应用,一同步入氢能时代。

Recent Advances in Hydrogen Generation Methods and Its Prospects for Applications in Fuel Cell

The present situation and developing trend of energy utilization worldwide were discussed briefly in this paper.The properties of hydrogen were presented,and recent advances in hydrogen generation methods were reviewed.As an attractive alternativeenergy source,hydrogen energy has been studied widely and intensively.Among the three hydrogen generation modes,(1) with chemical methods(2) from electrolysis of water(3) by biologic methods,the first was the major method for massproduction of hydrogen,in which catalysis reforming holds a large proportion of the total output.Along with the developments of fuel cell echniques, novel hydrogen generation techniques had attracted more and more attention.These hydrogen generation techniques have a promising future in the coming hydrogen age,accompanied with the R&D of fuel cells and hydrogen engines.
