Development of novel oxide protonics materials based on low-temperature fabrication processes

为了开发一种新型的质子导电氧化物材料，人们对低温制备工艺进行了研究，以避免合成过程中高温处理时质子载流子的损失。新的质子导电材料已经被开发出来，这种材料在合成过程中将相当数量的质子保留在其本体结构中。此外，还论证了利用纳米陶瓷弱结合的晶界作为可能的导电途径开发新型质子导电材料的可行性。

In order to develop a new class of proton-conducting oxide materials, investigations have been made on low-temperature fabrication process, which avoids loss of protonic carrier during high-temperature treatment for synthesis. New proton-conducting materials have been developed, which retain appreciable amount of protons in their bulk structure incorporated during synthesis. In addition, a feasibility has been demonstrated for development of new proton-conducting materials based on nano-structured ceramics which make use of their weakly bonded grain boundary as a possible conduction path.
