The aim of this work is to develop an electrochemical hydrogen pump which can regulate hydrogen partial pressure in mixed gases arbitrarily. For this purpose, we have studied on hydrogen sensor and electrochemical hydrogen permeation using a proton conducting ceramics, and devised to combine them to make hydrogen pump.1. Hydrogen sensor for hydrogen pump.Various galvanic type hydrogen sensors suitable for hydrogen pump were tried to fabricate using a proton conducting ceramic as a solid electrolyte and the best condition for pump could be determined.2. Test of electrochemical hydrogen permeation.Faradaic hydrogen permeation through SrCeo 3-based ceramics in hydrogen atmosphere at high temperature could be confirmed, and the best way for the pump was determined.3. Trial fabrication of hydrogen regulator.Based on the above described result, we could develop a new type hydrogen regulator, which consisted a hydrogen pump made of tubular type SrCe_<0.95>Yb_<0.05>O_<3-alpha> ceramic and two hydrogen sensors located on inlet and outlet side of the tube.4. Search of proton conducting ceramics for hydrogen pump.Some zirconate ceramics based on CaZrO_3 and SrZrO_3 were found to be protonic conductors which were stable against carbonmonoxide at high temperature.

本工作的目的是研制一种能任意调节混合气体中氢分压的电化学氢泵。为此，我们利用质子导电陶瓷对氢传感器和电化学氢渗透进行了研究，并设计将两者结合起来制造氢泵。氢泵用氢传感器。以质子导电陶瓷为固体电解质，尝试制备了各种适用于氢泵的电偶型氢传感器，确定了氢泵的最佳制备条件。电化学氢渗透试验。证实了srce3基陶瓷在高温氢气氛下的法拉第氢渗透，并确定了泵的最佳方式。氢调节器的试制。基于上述结果，我们可以研制出一种新型的氢调节器，它由管状SrCe_<0.95>Yb_<0.05>O_<3- α >陶瓷制成的氢泵和位于管状进出口侧的两个氢传感器组成。氢泵用质子导电陶瓷的研究。发现了一些以CaZrO_3和SrZrO_3为基料的锆酸盐陶瓷是在高温下对一氧化碳稳定的质子导体。
