摘　　要：对中温相变蓄热材料(PCM)的定义范畴、应用领域、国内外发展现状进行了评述.中温PCM主要针对90～550℃的热动力环境,在太阳能热发电、有机朗肯循环、移动蓄热技术、分布式能源系统等方面有广阔的应用前景.指出进一步的研究方向是拓展中温PCM的应用场合,规范长期稳定性的表征与测试手段,重视与换热器开发以及应用领域的整合,并提出硝酸盐熔融盐混和物将是今后一段时期内中温PCM研发和培育的重点产品对象.The definition, category, applications, and current development status of medium-temperature phase change materials （PCM） are reviewed. These PCM have a promising application in thermodynamic environment with its temperature varying from 90 to 550℃, especially in solar thermal power, organic Rankine cycle, mobile thermal energy storage and distributed energy resources system. It is pointed out that the further development direction is to exploit application fields, rationalize the characterization and exchanger and applications. And commercial PCM. t technique for long-term stability, and integrate with the development of heat molten nitrate salt mixtures are also suggested to be near-term solutions and potential
